Summary
Anxiety can affect far more than your thoughts.
You may feel constantly tense, frightened, irritable or mentally exhausted. You may overthink conversations, fear something bad is about to happen, repeatedly check your health, avoid driving or travelling, struggle socially, experience panic attacks or find that your world is gradually becoming smaller because ordinary situations no longer feel manageable.
The physical symptoms can be equally powerful. Anxiety may contribute to palpitations, chest tightness, trembling, dizziness, nausea, reflux, diarrhoea, constipation, headaches, muscle tension, disrupted sleep and profound fatigue.
Yet not every symptom that feels like anxiety is caused by anxiety alone.
Sleep loss, thyroid dysfunction, hormonal changes, perimenopause, medication, caffeine, nicotine, alcohol, blood glucose fluctuations, digestive problems, chronic pain, trauma-related hypervigilance, ADHD, autism and nutritional difficulties may all influence how you feel.
This is why good anxiety care should not begin with a single assumption about the cause.
A more useful starting point is:
What is happening for this particular person, and what is keeping it going?
This guide explains anxiety disorders, anxiety symptoms, panic attacks, health anxiety, social anxiety, phobias, physical symptoms of anxiety, gut brain symptoms, hormones, nutrition, trauma-related difficulties, ADHD, autism, sleep, addictions, relationships and the treatment approaches that may help.

What Is Anxiety?
Anxiety is part of your protective survival system.
Your brain continuously assesses what is happening around you and inside your body. When something appears threatening, your nervous system can rapidly prepare you to respond.
Your heart may beat faster. Breathing may become quicker or shallower. Muscles tighten. Attention narrows. Digestion may change. Your mind becomes increasingly focused on identifying possible danger.
These reactions can be useful when there is genuine risk.
Problems develop when the alarm becomes highly sensitive, remains active after the original threat has passed or repeatedly responds to ordinary situations as though something dangerous is about to happen.
You may logically know that you are safe and still feel physically terrified.
That apparent contradiction is one reason anxiety can feel so confusing.
According to the World Health Organization, anxiety disorders are among the most common mental health conditions worldwide.
World Health Organization: Anxiety Disorders
Anxiety is common, but common does not mean insignificant.
When anxiety begins controlling where you go, what you eat, how you sleep, who you see, how you work or what you believe you can cope with, it deserves proper assessment.
For individual therapeutic support, learn more about Counselling and Psychotherapy at Claire Russell Therapy.
When Does Normal Anxiety Become an Anxiety Disorder?
It is normal to feel nervous before an examination, interview, medical procedure, public presentation or difficult conversation.
The important distinction is not simply whether anxiety exists.
It is how persistent, intense and restrictive it has become.
| Everyday anxiety | Possible anxiety disorder |
|---|---|
| Usually linked to a recognisable situation | May occur repeatedly without immediate danger |
| Reduces when the situation passes | Continues for weeks, months or longer |
| Feels uncomfortable but manageable | Feels extremely difficult to control |
| Does not substantially restrict life | Begins to control travel, work, education, relationships or health behaviour |
| Reassurance may occasionally help | Reassurance becomes repeatedly necessary |
| Physical symptoms are temporary | Physical symptoms become frequent and frightening |
| You continue doing most ordinary activities | Avoidance gradually increases |
| You remain reasonably confident in your judgement | Anxiety repeatedly overrides what you logically know |
One of the most clinically useful questions is not simply:
How anxious are you?
It is:
What has anxiety persuaded you to stop doing?
That may include driving, eating away from home, travelling, speaking in meetings, exercising, sleeping alone, attending social events, making telephone calls, attending medical appointments or trusting ordinary physical sensations.
For repeated fear around illness and bodily sensations, read Health Anxiety in Ireland: A Clinical, Nutritional and Neuroscience Guide.
Anxiety and Mental Health in Ireland
Anxiety is an important mental health issue across Ireland.
The Central Statistics Office Irish Health Survey 2024 reported that 70.7 per cent of adults rated their mental health as good or very good. Among adults aged 18 to 24, the figure was 50.8 per cent.
Irish research has also identified substantial levels of psychological distress across the population.
These statistics should be interpreted carefully.
A population statistic cannot diagnose an individual person.
A proper assessment needs to consider your own symptoms, history, physical health, sleep, relationships, environment and daily functioning.
Important questions include:
- When did the anxiety begin?
- Was there an obvious trigger?
- Is the anxiety constant or episodic?
- Are panic attacks present?
- Are you avoiding situations?
- How are you sleeping?
- Are there digestive symptoms?
- Have hormones changed?
- Is medication relevant?
- Are caffeine, nicotine or alcohol contributing?
- Could ADHD or autism be involved?
- Is there a history of trauma-related difficulties?
- Are work, financial, educational or relationship pressures maintaining the problem?
For anxiety occurring alongside depression, overwhelm or loss, read Anxiety, Depression, Overwhelm, Sadness, Grief and Loss.
Emotional, Cognitive and Physical Symptoms of Anxiety
Anxiety can affect thoughts, emotions, behaviour and physical sensations.
Some people mainly experience worry.
Others describe the physical sensations as the most frightening part.
Emotional Symptoms of Anxiety
You may experience:
- Persistent dread
- Fear without a clear reason
- Irritability
- Feeling constantly on edge
- Fear of losing control
- Feeling overwhelmed

- Fear that you will not cope
Cognitive Symptoms of Anxiety
Common patterns include:
- Constant overthinking
- Catastrophising
- Replaying conversations
- Intrusive thoughts
- Difficulty concentrating
- Indecisiveness
- Repeated reassurance seeking
- Excessive planning
- Scanning for danger
- Assuming the worst
- Difficulty trusting your judgement

- Feeling that your surroundings are unreal
These sensations can be intense.
They should not automatically be dismissed as anxiety when they are new, severe, persistent or medically unexplained.
For persistent sleep difficulties, read Insomnia and Poor Sleep.
For persistent pain and nervous-system symptoms, read Chronic Pain in Ireland.
The Main Types of Anxiety Disorders
Anxiety disorders are not all the same.
The fear may centre on uncertainty, bodily sensations, social judgement, separation, particular objects or situations.
Several patterns may occur together.
Generalised Anxiety Disorder
Generalised Anxiety Disorder, or GAD, involves persistent and difficult-to-control worry across several areas of life.
You may worry about:
- Health
- Family
- Money
- Work
- Education
- Relationships
- Future events
- Mistakes
- Safety
- Whether you have forgotten something
- Whether something bad is about to happen
Your mind may feel as though it is continuously searching for the next problem.
Physical symptoms may include muscle tension, fatigue, irritability, poor concentration and disturbed sleep.
Panic Attacks
A panic attack is a sudden surge of intense fear or physical alarm.
Symptoms may include:
- Racing heart
- Chest discomfort
- Breathlessness
- Dizziness
- Shaking
- Sweating
- Nausea
- Tingling
- Feeling detached
- Fear of fainting
- Fear of dying
- Fear of losing control
A panic attack can feel medically dangerous.
New, severe or unexplained symptoms still deserve medical assessment.
Panic Disorder
Panic disorder may develop when repeated panic attacks are followed by persistent fear of another attack or significant behavioural restriction.
You may begin:
- Avoiding driving
- Avoiding public transport
- Avoiding crowded shops
- Remaining close to home
- Checking your heart rate
- Avoiding exercise
- Avoiding caffeine
- Repeatedly seeking reassurance
The fear of another panic attack can gradually become as limiting as the attack itself.
Social Anxiety Disorder
Social anxiety is more than ordinary shyness.
It involves persistent fear of embarrassment, judgement, rejection or negative evaluation.
You may:
- Avoid meetings
- Avoid presentations
- Struggle with telephone calls
- Fear eating in public
- Rehearse what you are going to say
- Avoid eye contact
- Analyse conversations afterwards
- Assume people noticed every sign of nervousness
- Turn down opportunities you genuinely want
Someone experiencing social anxiety may look quiet or distant while internally feeling intensely self-conscious.
Agoraphobia
Agoraphobia involves fear of situations in which escape may feel difficult or help may not be readily available.
This can include:
- Public transport
- Crowded places
- Shops
- Queues
- Motorways
- Open spaces
- Enclosed venues
- Travelling far from home
- Leaving home alone
The fear may centre on panic, fainting, becoming ill, needing a toilet or being unable to leave.
Specific Phobias
A specific phobia is an intense fear associated with a particular object, animal or situation.
Examples include:
- Flying
- Needles
- Blood
- Vomiting
- Dental treatment
- Heights
- Driving
- Dogs
- Spiders
- Enclosed spaces
- Medical procedures
Separation Anxiety Disorder
Separation anxiety may occur in children and adults.
Symptoms may include:
- Extreme distress before separation
- Fear that a loved one will be harmed
- Repeated checking
- Difficulty sleeping alone
- Avoiding work or school
- Physical symptoms when separation is anticipated
Selective Mutism
Selective mutism is an anxiety-related condition in which a child can speak comfortably in some settings but is consistently unable to speak in others.
A child may speak normally at home but become unable to speak at school or around unfamiliar people.
This is not deliberate defiance.
Pressure or punishment may intensify the response.

The Claire Russell Five-Layer Anxiety Assessment Framework
Claire Russell Therapy Clinical Framework
When I assess anxiety, I consider five interacting layers rather than assuming that every symptom has one cause.
| Layer | Clinical focus | Questions I consider |
|---|---|---|
| 1 | Anxiety pattern | Is this mainly generalised worry, panic, health anxiety, social anxiety, a phobia, separation anxiety or another presentation? |
| 2 | Psychological and nervous-system factors | Are trauma-related responses, avoidance, intrusive thoughts, perfectionism, grief, chronic stress or relationship difficulties involved? |
| 3 | Neurodivergent factors | Could ADHD, autism, sensory overload, masking or executive functioning demands be contributing? |
| 4 | Physical and nutritional factors | Are sleep, digestion, blood glucose, thyroid function, hormones, medication, caffeine, alcohol or nutritional deficiencies relevant? |
| 5 | Maintaining environment | Are work pressure, school demands, caregiving, relationship cycles, financial strain, bullying or unsuitable environments keeping the alarm active? |
Why These Five Layers Matter
Two people may say exactly the same thing:
“I have anxiety.”
Yet their clinical pictures may be completely different.
One person may have panic attacks maintained by fear of bodily sensations.
Another may be experiencing trauma-related hypervigilance.
A teenager may be overloaded by sensory and social demands.
A woman in perimenopause may be experiencing disrupted sleep, palpitations and increased nervous-system reactivity.
Someone else may be using alcohol every evening to switch off, only to experience stronger anxiety the following morning.
The label alone does not tell us what needs to change.
The pattern does.
Where clinically appropriate, my work may draw on Counselling and Psychotherapy, Clinical Hypnotherapy, Clinical Medical Hypnotherapy and RTT, and Registered Nutritionist Services.
The Claire Russell Anxiety Pattern Map
Claire Russell Therapy Clinical Framework
| What you notice first | Possible factors underneath | What may deserve assessment |
|---|---|---|
| Constant overthinking | Intolerance of uncertainty, perfectionism or threat monitoring | GAD, trauma-related stress, ADHD, sleep and environmental pressure |
| Sudden palpitations | Panic, hormones, medication, caffeine or physical illness | Panic disorder, thyroid function, medication and cardiac symptoms |
| Fear of social situations | Fear of judgement, previous criticism or masking | Social anxiety, autism, trauma-related experiences and confidence |
| IBS before travelling | Digestive symptoms combined with fear of losing control | Gut health, eating patterns, anticipatory anxiety and avoidance |
| Anxiety on waking | Poor sleep, alcohol, hormonal changes or anticipatory worry | Sleep, substance use, nutrition and psychological stress |
| Repeated symptom checking | Temporary reassurance reinforcing fear | Health anxiety, OCD and appropriate medical investigation |
| Anxiety after drinking | Rebound nervous-system activation and disrupted sleep | Alcohol intake, dependence, sleep and psychological triggers |
| Anxiety during perimenopause | Hormonal fluctuation interacting with sleep and stress | Menopause symptoms, thyroid function, nutrition and previous anxiety |
| School refusal | Fear, overload, bullying or separation anxiety | School environment, ADHD, autism, trauma and family circumstances |
| Anxiety in crowded places | Threat sensitivity or sensory overload | Social anxiety, panic, ADHD, autism and sensory processing |

For intrusive thoughts and checking behaviours, read OCD, Intrusive Thoughts, Compulsions and the Anxiety Loop.
Anxiety, Overstimulation and Nervous-System Overload
Anxiety and overload are not identical.
Anxiety generally involves anticipation of threat.
Overload occurs when sensory, cognitive, social, emotional or physical demands exceed your current capacity to process them comfortably.
| Anxiety may involve | Overload may involve |
|---|---|
| Fear about what might happen | Too much information arriving at once |
| Catastrophic predictions | Reduced processing capacity |
| Avoidance of perceived danger | Withdrawal because the environment is genuinely overwhelming |
| Reassurance seeking | Need for quiet, reduced demands or recovery |
| Threat monitoring | Difficulty filtering noise, movement or competing information |
| Fear-driven restriction | Exhaustion-driven restriction |
This distinction can be particularly important when ADHD, autism, migraine, poor sleep, chronic pain, trauma-related hypervigilance or hormonal changes are present.
A person overwhelmed by bright lighting, background conversation, crowds and constant interruptions may not simply need to tolerate more anxiety.
The environment may need adjustment too.
Read my detailed resource on Overstimulation and Sensory Overload: Signs, Causes and How to Reduce an Overloaded Nervous System.
Conditions That Can Resemble or Overlap with Anxiety
Obsessive Compulsive Disorder
Obsessive Compulsive Disorder, or OCD, involves intrusive thoughts, images, doubts or urges together with repetitive behaviours or mental rituals intended to reduce distress.
Examples include:
- Repeated checking
- Excessive washing
- Counting
- Mentally reviewing events
- Repeating phrases
- Seeking certainty
- Confessing
- Repeated reassurance seeking
Reassurance may help briefly.
Then the doubt returns.
This is why repeated reassurance can sometimes strengthen rather than resolve an OCD cycle.
Read OCD Help Ireland: Intrusive Thoughts, Compulsions and the Anxiety Loop.
Trauma-Related Difficulties
Trauma-related symptoms may include:
- Hypervigilance
- Exaggerated startle responses
- Nightmares
- Intrusive memories
- Avoidance
- Emotional numbness
- Shame
- Anger
- Dissociation
- Sleep disruption
- Difficulty trusting people
- Persistent physical tension
These symptoms may resemble GAD, panic disorder or social anxiety.
Treatment needs to consider what the nervous system may have learned from previous overwhelming experiences.
Read Trauma Therapy and Trauma Hypnotherapy in Ireland and ONLINE for PTSD, Complex PTSD, OCD and Rumination.
You may also find Hypnotherapy for Trauma Recovery in Ireland helpful.
ADHD
ADHD may contribute to anxiety through:
- Difficulty organising tasks
- Fear of forgetting things
- Time-management difficulties
- Emotional reactivity
- Repeated criticism
- Rejection sensitivity
- Sleep disruption
- Academic pressure
- Workplace pressure
- Difficulty beginning tasks
- Difficulty finishing tasks
- Constantly feeling behind
What appears to be anxiety may partly reflect the strain of managing unsupported executive functioning difficulties.
Autism
Autistic people may experience anxiety around:
- Sensory overload
- Unexpected changes
- Social uncertainty
- Communication demands
- Busy environments
- Transitions
- Masking
- Previous bullying
- Unclear expectations
Intervention should consider the environment rather than assuming the person simply needs to tolerate more discomfort.
Depression
Anxiety and depression frequently occur together.
Someone may feel mentally restless yet physically exhausted.
They may alternate between worry, agitation, irritability, low mood, hopelessness and withdrawal.
Addictions and Compulsive Behaviours
Alcohol, nicotine, vaping, drugs, gambling, pornography, food and other compulsive behaviours may temporarily reduce emotional distress.
That short-term relief can reinforce the behaviour.
Over time, withdrawal, shame, poor sleep, financial stress and relationship problems may intensify anxiety.
Read Addiction Help in Ireland.
Physical Symptoms That Should Not Automatically Be Assumed to Be Anxiety
Anxiety can cause powerful physical symptoms.
That does not mean every physical symptom is caused by anxiety.
Possible contributors include:
- Thyroid dysfunction
- Iron deficiency
- Vitamin B12 deficiency
- Folate deficiency
- Blood glucose disruption
- Cardiac rhythm problems
- Medication side effects
- Excess caffeine
- Nicotine
- Stimulants
- Alcohol withdrawal
- Sleep apnoea
- Chronic pain
- Perimenopause
- Pregnancy
- Postnatal changes
- Neurological conditions
- Digestive disease
- Infection
- Inflammatory illness
| Symptom | Anxiety may contribute through | Medical assessment is especially important when |
|---|---|---|
| Palpitations | Adrenaline and increased heart rate | New, irregular, prolonged or associated with fainting |
| Chest tightness | Muscle tension or altered breathing | Severe, unfamiliar or associated with significant pain |
| Dizziness | Hyperventilation or panic | Sudden, persistent or associated with weakness or collapse |
| Breathlessness | Rapid or shallow breathing | Severe, new or present at rest |
| Trembling | Adrenaline | Persistent, progressive or unrelated to stress |
| Fatigue | Poor sleep and prolonged tension | Severe or unexplained |
| Weight change | Appetite changes | Rapid or unexplained |
| Bowel changes | Gut brain signalling | Blood, fever, unexplained weight loss or persistent pain |
| Headaches | Tension and sleep disruption | Sudden, severe or accompanied by neurological symptoms |
Seek urgent medical help for severe chest pain, significant breathing difficulty, fainting, seizures, new neurological weakness or sudden confusion.
Read more about the overlap between physical symptoms, nervous-system responses and Chronic Pain in Ireland.
The Gut Brain Axis, IBS and Anxiety
The digestive system and brain communicate continuously.
This communication network is commonly called the gut brain axis.
It involves:
- The nervous system
- The vagus nerve
- Stress hormones
- Immune signalling
- Gut microorganisms and their metabolites
- Nutrient availability
- Intestinal function
This helps explain why emotional stress can affect digestion and why digestive symptoms can increase anxiety.
You may notice:
- IBS becoming worse during stressful periods
- Diarrhoea before travelling
- Nausea during panic
- Reflux before an important event
- Appetite loss when worried
- Bloating during prolonged stress
- Fear of being unable to reach a toilet
- Avoiding restaurants because of digestive symptoms
IBS, Toilet Anxiety and Fear of Travelling
Digestive urgency can become particularly restrictive.
Imagine experiencing severe bowel urgency while stuck in traffic once.
Afterwards, your brain may begin predicting that the same thing will happen again.
You begin planning journeys around toilets.
Then you avoid motorways.
Then restaurants.
Then travelling with other people.
The original problem may have been digestive.
The maintaining problem may now involve both digestion and anxiety.
A comprehensive approach may need to address:
- Digestive symptoms
- Food restriction
- Meal timing
- Fear of embarrassment
- Anticipatory anxiety
- Reassurance behaviours
- Avoidance
- Gradual re-engagement with ordinary activities
The digestive symptoms should not be dismissed.
The anxiety surrounding them should not be ignored either.
Read IBS, Bloating, Reflux and Gut Health Treatment in Ireland.
Registered Nutritionist support is available through Registered Nutritionist Services in Ireland and ONLINE.
Clinical Hypnotherapy and Clinical Medical Hypnotherapy may also be relevant when digestive symptoms and anticipatory anxiety interact. Read about Clinical Hypnotherapy, Clinical Medical Hypnotherapy, Hypnosis and RTT.
Hormones, Thyroid Function, Perimenopause and Anxiety
Thyroid Function and Anxiety-Like Symptoms
An overactive thyroid can produce symptoms that resemble anxiety, including:
- Palpitations
- Trembling
- Heat intolerance
- Sweating
- Weight loss
- Restlessness
- Difficulty sleeping
An underactive thyroid may contribute to fatigue, low mood, cognitive changes and reduced tolerance of stress.
Thyroid assessment may be appropriate where symptoms or medical history suggest concern.
Perimenopause, Menopause and Anxiety
For some women, anxiety changes significantly during perimenopause.
Possible symptoms include:
- Sudden anxiety
- Panic sensations
- Palpitations
- Hot flushes
- Night waking
- Irritability
- Reduced stress tolerance
- Difficulty concentrating
- Mood changes
- Increased sensitivity to caffeine or alcohol
It can be unhelpful to assume that everything is hormonal.
It is equally unhelpful to dismiss hormonal changes and treat everything as psychological.
A joined-up assessment may consider:
- Perimenopause
- Thyroid function
- Sleep
- Nutrition
- Alcohol
- Caffeine
- Medication
- Previous anxiety
- Trauma history
- Work pressure
- Caregiving
- Relationship stress
Registered Nutritionist Services may be useful when anxiety occurs alongside hormonal, thyroid, digestive, fatigue or metabolic concerns.
Read about Registered Nutritionist Services.
Anxiety During Pregnancy and After Birth
Anxiety may emerge or intensify during pregnancy or following childbirth.
Concerns may centre on:
- The baby’s health
- Childbirth
- Feeding
- Responsibility
- Sleep deprivation
- Previous pregnancy loss
- Birth-related distress
- Intrusive thoughts
- Identity changes
- Relationship pressure
Severe confusion, hallucinations or major behavioural changes following childbirth require urgent specialist medical assessment.
Blood Glucose, Eating Patterns and Anxiety-Like Symptoms
Long periods without food, restrictive dieting or inadequate energy intake can produce physical symptoms that resemble anxiety.
These may include:
- Shakiness
- Sweating
- Irritability
- Palpitations
- Weakness
- Difficulty concentrating
- Urgent hunger
- Feeling suddenly overwhelmed
For some people, regular balanced meals may reduce these physical fluctuations.
A balanced meal will often include:
- Protein
- Fibre-rich carbohydrate
- Vegetables or fruit
- An appropriate source of fat
Nutrition should be individualised where diabetes, reactive hypoglycaemia, digestive disease, pregnancy, medication or eating disorders are relevant.
Registered Nutritionist input may be particularly valuable when anxiety occurs alongside:
- Food restriction
- Binge eating
- Emotional eating
- Digestive symptoms
- Blood glucose concerns
- Fatigue
- Nutritional deficiencies
- Food addiction
- Sugar addiction
For individual assessment, visit Registered Nutritionist Services in Ireland.
Nutritional Deficiencies and Anxiety Symptoms
Nutrition is not a simple cure for anxiety disorders.
However, deficiencies or inadequate intake can contribute to physical symptoms that increase emotional distress.
Iron
Iron deficiency may contribute to:
- Fatigue
- Reduced exercise tolerance
- Palpitations
- Headaches
- Poor concentration
- Breathlessness
These symptoms can be frightening and may intensify anxiety.
Vitamin B12 and Folate
Deficiencies may affect neurological function, energy and cognition.
Persistent tingling, weakness, cognitive change or unexplained fatigue deserves medical assessment.
Vitamin D
Vitamin D plays several roles in normal health.
Supplementation should be based on individual need rather than assuming high-dose supplementation will treat anxiety.
Magnesium
Magnesium is involved in nervous-system and muscular function.
Although magnesium is widely promoted for stress and anxiety, supplementation should be individualised, particularly where kidney disease, medication or other medical conditions are present.
Restrictive Diets and Food Anxiety
Highly restrictive eating can sometimes worsen anxiety.
A person may begin removing numerous foods because they fear:
- Symptoms
- Inflammation
- Intolerances
- Allergic reactions
- Digestive reactions
- Weight gain
- Loss of control
This can increase:
- Nutritional risk
- Food anxiety
- Social restriction
- Gastrointestinal sensitivity
- Obsessive checking
- Fear around eating
A Registered Nutritionist consultation can help distinguish an appropriate dietary intervention from unnecessary restriction.
Inflammation, Autoimmune Conditions and Anxiety
Chronic inflammatory and autoimmune conditions can affect pain, energy, digestion, sleep and quality of life.
Examples include:
- Coeliac disease
- Hashimoto’s thyroiditis
- Rheumatoid arthritis
- Psoriasis
- Crohn’s disease
- Ulcerative colitis
- Other inflammatory and autoimmune conditions
Living with unpredictable symptoms can understandably increase anxiety.
Medication effects, chronic pain, disrupted sleep and restricted diets may add further strain.
The relationship is complex.
It would be inaccurate to claim that inflammation alone explains every anxiety disorder.
Where anxiety occurs alongside autoimmune symptoms, persistent fatigue or digestive problems, an integrated assessment may be appropriate.
Registered Nutritionist Services may help assess dietary adequacy, digestive symptoms, nutrient status and relevant eating patterns alongside appropriate medical care.

Sleep, Insomnia and Anxiety
Sleep and anxiety can reinforce each other.
Poor sleep may increase:
- Irritability
- Physical tension
- Sensitivity to bodily sensations
- Difficulty concentrating
- Emotional reactivity
- Catastrophic thinking
- Overstimulation
- Reduced tolerance of uncertainty
Anxiety can then make sleep harder.
You may lie awake thinking:
“What if I cannot sleep?”
“What if I cannot function tomorrow?”
“What if something is wrong with me?”
Sleep assessment may need to consider:
- Bedtime anxiety
- Night waking
- Alcohol
- Caffeine
- Sleep apnoea
- Perimenopause
- Menopause
- Pain
- Medication
- Restless legs
- Shift work
- Trauma-related nightmares
- Irregular sleep schedules
Read Insomnia and Poor Sleep.
Clinical Hypnotherapy may also form part of a broader plan when sleep difficulty is closely linked with anxiety or persistent mental overactivity.
Learn more about Clinical Hypnotherapy and Clinical Medical Hypnotherapy.
Caffeine, Alcohol, Nicotine, Vaping, Drugs and Anxiety
Caffeine and Anxiety
Caffeine may increase alertness, but higher intake can also contribute to:
- Palpitations
- Trembling
- Restlessness
- Difficulty sleeping
- Gastrointestinal symptoms
- Increased physical anxiety
Individual sensitivity varies.
Alcohol and Anxiety
Alcohol can initially feel calming.
However, it can disrupt sleep and contribute to rebound anxiety as its effects wear off.
A pattern can develop:
Anxiety → alcohol → temporary relief → disrupted sleep → stronger anxiety → more alcohol
Nicotine, Smoking and Vaping
Nicotine can temporarily alter mood and concentration.
Dependence and withdrawal may contribute to irritability, tension and anxiety.
Drug Use and Anxiety
Stimulants, cannabis and other recreational substances can alter anxiety, mood, sleep and perception.
Some people experience panic attacks or persistent fear after an intense drug experience.
Where substance use and anxiety occur together, both should be assessed.

The Claire Russell Anxiety and Avoidance Cycle
Claire Russell Therapy Clinical Framework
| Stage | What happens |
|---|---|
| 1. Trigger | A thought, situation, memory or physical sensation appears |
| 2. Prediction | Your mind predicts danger, embarrassment, illness or loss of control |
| 3. Alarm | Heart rate, breathing and physical tension increase |
| 4. Safety behaviour | You escape, check, cancel, seek reassurance or ask someone else to take over |
| 5. Relief | Anxiety temporarily reduces |
| 6. Learning | Your brain interprets avoidance as evidence that danger was real |
| 7. Restriction | The situation feels even harder next time |
Avoidance is compelling because it often works immediately.
The longer-term cost is that your brain may never receive evidence that the feared outcome would not have happened.
Examples include:
- Leaving a supermarket when anxiety rises
- Repeatedly checking your pulse
- Asking your partner for reassurance
- Avoiding driving
- Cancelling social events
- Repeatedly researching symptoms
- Asking someone else to make telephone calls
- Avoiding food because you fear digestive symptoms
The goal is not to force yourself into overwhelming situations.
It is to reduce unnecessary restriction carefully and appropriately.
What More Than 20 Years of Clinical Work Has Taught Me About Anxiety
Over more than 20 years of clinical work, I have repeatedly seen that anxiety rarely exists in isolation.
A person may arrive focused entirely on panic attacks, but poor sleep, IBS, perimenopause or alcohol may be increasing their physical symptoms.
Someone else may describe themselves as an anxious person after years of managing unsupported ADHD.
A teenager may appear avoidant when the real picture includes sensory overload, social pressure or fear of humiliation.
Another person may have become so accustomed to hypervigilance after frightening experiences that they no longer recognise how continuously alert they are.
This is why I often ask:
What changed before the anxiety became worse?
What physical symptoms appeared at the same time?
What are you now avoiding?
What do you repeatedly check?
What reassurance do you repeatedly seek?
What does anxiety prevent you from doing?
What helps temporarily but makes things worse later?
One particularly revealing question is:
How much smaller has your life become?
Someone might say:
“I stopped driving.”
“I cannot stay in a hotel.”
“I never eat before travelling.”
“I cannot let my child go anywhere without me.”
“I avoid meetings.”
“I no longer exercise because I am frightened of my heart rate.”
“I spend hours checking symptoms.”
Those answers matter.
Treatment is not only about reducing an uncomfortable feeling.
It is about helping someone participate in life again.
Four Anonymised Irish Clinical Illustrations
These illustrations combine commonly encountered clinical patterns. Identifying details have been changed. They are educational examples and do not predict an individual outcome.
Clinical Illustration One: Panic, IBS and Motorway Avoidance
A woman in her late 30s in County Limerick had stopped driving on motorways after experiencing sudden bowel urgency while travelling.
Her anxiety was not simply fear of driving.
Assessment identified:
- IBS symptoms
- Fear of embarrassment
- Skipped meals
- High caffeine intake
- Constant toilet planning
- Increasing travel avoidance
The clinical plan therefore needed to consider digestive symptoms and the anxiety cycle together.
Clinical Illustration Two: Perimenopause and Night-Time Anxiety
A woman in her late 40s attending online from Cork developed sudden night-time anxiety.
She described:
- Palpitations
- Repeated waking
- Hot flushes
- Increased sensitivity to alcohol
- Catastrophic thoughts about her health
Assessment considered perimenopause, sleep, caffeine, alcohol, thyroid symptoms, workload and previous anxiety.
It would have been too simplistic to treat the problem as purely psychological.
Clinical Illustration Three: Teenager with School Anxiety and Overload
A teenager described stomach pain every morning before school.
The initial concern was anxiety.
Further assessment identified:
- Sensory overload
- Fear of social mistakes
- Difficulty concentrating
- Poor sleep
- Exhaustion after school
- Possible neurodivergent needs
The plan therefore needed to consider school demands and sensory factors rather than simply asking the teenager to tolerate more distress.
Clinical Illustration Four: Anxiety and Alcohol Reliance
An adult attending online from Dublin used alcohol most evenings to stop persistent worry.
The alcohol worked quickly.
The following day, anxiety was stronger.
Sleep was disrupted, physical symptoms increased and alcohol gradually became an increasingly important coping strategy.
Treatment needed to address both the anxiety and the function alcohol had begun to serve.
What Actually Helps Anxiety?
There is no single treatment that is best for every person.
The appropriate plan depends on:
- The anxiety pattern
- Severity
- Age
- Physical health
- Neurodivergence
- Trauma history
- Medication
- Substance use
- Digestive symptoms
- Hormonal symptoms
- Sleep
- Previous treatment
- Personal preferences
Counselling and Psychotherapy for Anxiety
Counselling and Psychotherapy may help you:
- Understand triggers
- Identify catastrophic thinking
- Work with uncertainty
- Reduce avoidance
- Reduce reassurance seeking
- Address trauma-related patterns
- Understand shame and self-criticism
- Improve communication
- Strengthen confidence
- Develop a more accurate sense of risk
- Re-engage with avoided situations
Learn more about Counselling and Psychotherapy in Ireland and ONLINE.
Behavioural and Exposure-Based Approaches
Appropriate exposure-based work has good evidence for several anxiety disorders.
It involves gradually approaching feared but safe situations rather than repeatedly escaping them.
Examples may include:
- Remaining in a shop slightly longer
- Driving one additional motorway junction
- Making a telephone call yourself
- Eating in a quieter restaurant
- Allowing a harmless bodily sensation to settle without checking it
- Delaying reassurance seeking
- Attending part of an event rather than cancelling completely
Exposure should be thoughtful and collaborative.
It should not involve forcing someone into a genuinely unsafe or unsuitable environment.
Clinical Hypnotherapy for Anxiety
Clinical Hypnotherapy may be incorporated into a broader plan for:
- Anticipatory anxiety
- Physical tension
- Fear associations
- Panic-related fear
- Sleep difficulties
- Confidence
- Avoidance
- Habitual responses
- Compulsive coping patterns
Hypnosis involves focused attention and therapeutic suggestion.
You remain aware and in control.
Clinical Hypnotherapy is not a replacement for necessary medical or psychiatric care.
Learn more about Clinical Hypnotherapy, Clinical Medical Hypnotherapy, Hypnosis and RTT in Ireland.
For an in-depth evidence-based explanation, read Clinical Hypnotherapy Ireland: History, Science and Evidence-Based Help for Trauma, Addictions, Anxiety, IBS and Stress.
Clinical Medical Hypnotherapy
Clinical Medical Hypnotherapy may be relevant where psychological and physical symptoms interact.
Examples include:
- Medical procedure anxiety
- Needle fear
- Dental anxiety
- Digestive symptoms
- Chronic pain
- Sleep disruption
- Anticipatory nausea
- Health-related fear
Medical causes should be appropriately investigated before unexplained symptoms are attributed to anxiety.
Rapid Transformational Therapy
RTT may be used to explore:
- Earlier experiences
- Recurring beliefs
- Fear associations
- Self-critical thinking
- Automatic emotional responses
- Avoidance
- Confidence difficulties
Suitability should be assessed individually.
Registered Nutritionist Services for Anxiety and Physical Symptoms
Registered Nutritionist input may be appropriate when anxiety occurs alongside:
- IBS
- Reflux
- Bloating
- Irregular eating
- Food restriction
- Emotional eating
- Blood glucose concerns
- Perimenopause
- Thyroid concerns
- Fatigue
- Nutritional deficiencies
- Autoimmune conditions
- Food addiction
- Alcohol use
- High caffeine intake
The aim is not to turn food into another source of anxiety.
It is to identify relevant nutritional factors without unnecessary restriction.
Learn more about Registered Nutritionist Services in Ireland and ONLINE.
Medication for Anxiety
Medication may benefit some people, particularly when anxiety is moderate or severe.
Medication decisions should be discussed with a GP, psychiatrist or appropriately qualified prescriber.
Do not suddenly stop antidepressants, benzodiazepines or other prescribed medicines without medical guidance.
Couples Counselling and Marriage Counselling
Anxiety can become embedded within relationships.
Examples include:
- Repeated reassurance
- Checking
- Jealousy
- Conflict avoidance
- Dependence
- Withdrawal
- Irritability
- Reduced intimacy
Couples Counselling or Marriage Counselling may help both people understand and change the cycle.
Learn more about Counselling, Psychotherapy, Couples Counselling and Marriage Counselling.
How Strong Is the Evidence?
| Intervention or consideration | Evidence position |
|---|---|
| Psychological therapies | Strong evidence for anxiety disorders, with the most appropriate approach varying by presentation |
| Exposure-based behavioural approaches | Strong evidence for several anxiety disorders and phobias |
| Prescribed medication | Established treatment option for some people |
| Sleep assessment | Clinically important because disrupted sleep can intensify anxiety |
| Caffeine and substance assessment | Important when physical anxiety or dependence is present |
| Nutritional assessment | Relevant where dietary insufficiency, digestive illness or food restriction exists |
| Gut microbiome interventions | Developing area and not a universal anxiety treatment |
| Clinical Hypnotherapy | May be integrated appropriately, with evidence varying by condition |
| RTT | Requires individual assessment |
| Highly restrictive diets | Not routinely justified without clear clinical indication |
| Unverified supplement protocols | Evidence, quality and safety vary |
Evidence-based care does not mean treating everybody identically.
It means combining:
- Research evidence
- Clinical judgement
- Safety
- Medical history
- Individual circumstances
- Your preferences and goals

Read Overstimulation and Sensory Overload.
The Anxiety Impact Check
This is an educational reflection tool, not a diagnostic test.
During the past four weeks, has anxiety affected your ability to:
- Sleep consistently?
- Travel independently?
- Drive?
- Attend work?
- Attend school or college?
- Eat regularly?
- Eat away from home?
- Spend time with other people?
- Make telephone calls?
- Attend appointments?
- Remain in shops or queues?
- Exercise without fear?
- Trust ordinary physical sensations?
- Disagree with someone?
- Make decisions without repeated reassurance?
- Allow a child or partner to be away from you?
- Complete ordinary household tasks?
- Rest without constant worry?
- Reduce alcohol, nicotine or compulsive behaviours?
- Participate in activities you previously enjoyed?
The number of items you recognise does not diagnose an anxiety disorder.
The pattern can help reveal where anxiety is having the greatest impact.
Seven Factors Commonly Missed in Anxiety Assessment
1. Sleep Disruption
Poor sleep can increase emotional reactivity, physical tension and sensitivity to threat.
Read Insomnia and Poor Sleep.
2. Medication and Substance Effects
Caffeine, nicotine, alcohol, stimulants and some prescribed medicines may contribute to anxiety-like symptoms.
3. Neurodivergent Overload
Someone may be responding to excessive demands rather than irrational fear alone.
Read Overstimulation and Sensory Overload.
4. Hormonal Transitions
Pregnancy, the postnatal period, perimenopause and menopause can affect sleep, mood and physical sensations.
5. Digestive Fear
A person may increasingly avoid travel, eating or social activities because they fear bowel symptoms, nausea or vomiting.
Read IBS, Bloating, Reflux and Gut Health.
6. Trauma-Related Hypervigilance
Persistent alertness may reflect previous overwhelming experiences rather than current danger.
Read Hypnotherapy for Trauma Recovery in Ireland.
7. Relationship Accommodation
Partners and parents can unintentionally strengthen anxiety by repeatedly providing reassurance, completing tasks or helping someone avoid every feared situation.
This does not mean removing kindness.
It means finding ways to remain supportive without allowing anxiety to make every decision.
Anxiety in Children and Teenagers
Children and teenagers do not always describe anxiety as worry.
Possible signs include:
- Stomach aches
- Headaches
- Tearfulness
- Irritability
- Angry outbursts
- School refusal
- Difficulty sleeping alone
- Repeated reassurance
- Perfectionism
- Fear of mistakes
- Social withdrawal
- Changes in eating
- Difficulty concentrating
- Increased screen use
- Loss of confidence
- Repeated requests to leave school
- Distress before activities
- Difficulty separating from parents
Assessment may also need to consider:
- Bullying
- Learning difficulties
- ADHD
- Autism
- Sensory overload
- Trauma-related experiences
- Sleep problems
- Bereavement
- Parental separation
- Academic pressure
- Family stress
- Physical health concerns
A child should not be labelled anxious simply because their behaviour is difficult.
Behaviour communicates something.
The important task is working out what.
For examination-related anxiety, read Exam Anxiety in Ireland.
For Leaving Certificate and Junior Cycle stress, read Leaving Cert Anxiety and Junior Cert Anxiety Ireland.
Children and teenagers may also access appropriate Counselling and Psychotherapy, Clinical Hypnotherapy and Registered Nutritionist Services.
Anxiety and Relationships
Anxiety can affect relationships in subtle ways.
It may contribute to:
- Repeated reassurance seeking
- Checking a partner’s whereabouts
- Fear of abandonment
- Jealousy
- Conflict avoidance
- Difficulty expressing needs
- Irritability
- Reduced intimacy
- Withdrawal
- Dependence
- Repeated apologising
- Difficulty making decisions
A partner may gradually feel responsible for preventing every anxious reaction.
This can unintentionally strengthen the pattern.
Relationship work may focus on:
- Communication
- Boundaries
- Emotional responsibility
- Reducing repeated reassurance
- Understanding fear-driven behaviour
- Restoring trust
- Managing conflict differently
- Reducing withdrawal
Relationship anxiety may also be influenced by betrayal, grief, separation, trauma-related experiences or fear of rejection.

When to Seek Urgent Help
Seek urgent medical assistance if you experience:
- New or severe chest pain
- Fainting
- Severe breathing difficulty
- Sudden confusion
- New weakness on one side
- Seizures
- Symptoms following an overdose
- Sudden severe headache
- A major change in consciousness
Seek immediate emergency or crisis support if you are at risk of harming yourself or another person.
Anxiety can produce intense physical sensations.
Serious medical symptoms should not be self-diagnosed as anxiety.
Frequently Asked Questions About Anxiety
1. What Are the Most Common Symptoms of Anxiety?
Common anxiety symptoms include excessive worry, overthinking, dread, restlessness, irritability, heart palpitations, chest tightness, dizziness, trembling, sweating, nausea, IBS symptoms, poor sleep, muscle tension and avoidance.
2. How Do I Know Whether I Have an Anxiety Disorder?
Anxiety may require professional assessment when it becomes persistent, difficult to control or begins interfering with work, education, sleep, health, relationships, travel or everyday activities.
3. What Does Severe Anxiety Feel Like Physically?
Severe anxiety may cause a racing heart, trembling, chest tightness, breathlessness, dizziness, sweating, nausea, tingling, muscle tension and a feeling that something terrible is about to happen.
New or severe symptoms should still be medically assessed when appropriate.
4. Can Anxiety Cause Heart Palpitations?
Yes. Adrenaline and nervous-system activation can increase heart rate and awareness of your heartbeat.
New, persistent or irregular palpitations should be discussed with a healthcare professional.
5. Can Anxiety Cause Chest Pain or Chest Tightness?
Anxiety may contribute through muscle tension, rapid breathing and nervous-system activation.
New, severe or unexplained chest pain requires medical assessment.
6. Can Anxiety Cause Dizziness and Light-Headedness?
Yes. Rapid breathing, muscle tension, panic and heightened physical awareness may contribute to dizziness.
Persistent or unexplained dizziness should not automatically be attributed to anxiety.
7. Can Anxiety Make You Feel Sick or Nauseous?
Yes. The nervous system and digestive system communicate closely. Anxiety may contribute to nausea, changes in appetite, reflux, abdominal discomfort and bowel changes.
8. Can Anxiety Cause IBS, Diarrhoea or Constipation?
Stress and anxiety can influence gut motility and sensitivity. IBS and anxiety may also reinforce each other through the gut brain axis.
Read IBS, Bloating, Reflux and Gut Health.
9. Can Anxiety Make You Feel Tired All the Time?
Persistent nervous-system activation, muscle tension, disrupted sleep, poor appetite and constant mental monitoring can contribute to fatigue.
Severe or unexplained tiredness also deserves medical assessment.
10. Can Poor Sleep Make Anxiety Worse?
Yes. Sleep disruption can increase emotional reactivity, physical sensitivity and difficulty concentrating.
Read Insomnia and Poor Sleep.
11. Can Perimenopause Cause Anxiety and Panic Attacks?
Hormonal fluctuations during perimenopause may coincide with anxiety, palpitations, sleep disruption, hot flushes and reduced stress tolerance.
Other possible contributors should still be considered.
12. Can Menopause Cause Anxiety?
Anxiety may emerge or worsen during the menopausal transition, particularly when hormonal changes interact with poor sleep, stress, physical symptoms and previous anxiety.
13. Can Thyroid Problems Feel Like Anxiety?
Yes. Thyroid dysfunction may contribute to palpitations, trembling, fatigue, temperature changes, sleep disruption and mood changes.
14. Can Iron Deficiency Feel Like Anxiety?
Iron deficiency may contribute to fatigue, breathlessness, palpitations, headaches and reduced concentration. These physical symptoms can feel frightening.
15. Can Low Blood Sugar Feel Like Anxiety?
Blood glucose changes can produce shakiness, sweating, weakness, irritability, hunger and palpitations that may resemble anxiety.
16. Can Caffeine Make Anxiety Worse?
Yes. Some people are particularly sensitive to caffeine and may experience increased palpitations, trembling, restlessness, digestive symptoms or insomnia.
17. Can Alcohol Make Anxiety Worse the Next Day?
Yes. Although alcohol may initially feel calming, it can disrupt sleep and contribute to rebound anxiety as its effects wear off.
18. Can Nicotine or Vaping Increase Anxiety?
Nicotine affects the nervous system, and both stimulation and withdrawal can contribute to anxiety, tension and irritability.
19. Can Trauma Cause Constant Anxiety?
Trauma-related hypervigilance can leave the nervous system continuously monitoring for possible danger.
Read Trauma Therapy and Trauma Hypnotherapy in Ireland.
20. Can PTSD Feel Like Generalised Anxiety?
Yes. Hypervigilance, sleep disruption, physical tension, intrusive memories and avoidance can sometimes resemble generalised anxiety.
21. Can ADHD Cause Anxiety?
ADHD may contribute to anxiety through executive functioning difficulties, time pressure, forgetfulness, emotional reactivity, repeated criticism and sleep disruption.
22. Can Autism Be Associated with Anxiety?
Yes. Sensory overload, unexpected change, social uncertainty, masking and unsuitable environments can increase anxiety for some autistic people.
23. What Is the Difference Between Anxiety and Sensory Overload?
Anxiety usually involves anticipation of threat. Sensory overload occurs when sensory or cognitive demands exceed the person’s current processing capacity. Both can occur together.
Read Overstimulation and Sensory Overload.
24. Is Health Anxiety a Real Anxiety Problem?
Yes. Health anxiety can involve persistent fear of serious illness, repeated checking, symptom research and reassurance seeking despite medical reassurance.
Read Health Anxiety in Ireland.
25. Is Anxiety Connected with OCD?
There can be overlap, particularly around intrusive thoughts, checking, uncertainty and reassurance seeking. OCD requires its own careful assessment.
Read OCD, Intrusive Thoughts and Compulsions.
26. Why Does Reassurance Only Help My Anxiety for a Short Time?
Reassurance can reduce anxiety temporarily. Repeated reassurance may teach the brain that certainty must be obtained before you can feel safe, which can strengthen the cycle.
27. Why Do I Keep Searching My Symptoms?
Searching often provides temporary certainty. When uncertainty returns, the urge to search may return too. This is particularly common in health anxiety and OCD-related checking.
28. Can Anxiety Affect Relationships?
Yes. Anxiety can contribute to repeated reassurance, jealousy, checking, withdrawal, irritability, fear of abandonment and conflict avoidance.
29. Can Couples Counselling Help When Anxiety Is Affecting a Relationship?
Couples Counselling or Marriage Counselling may help partners understand anxiety-related cycles, improve communication and establish healthier boundaries around reassurance and avoidance.
Learn more about Counselling, Psychotherapy, Couples Counselling and Marriage Counselling.
30. Can Children and Teenagers Have Anxiety Disorders?
Yes. Anxiety in younger people may appear as stomach aches, school avoidance, irritability, sleep problems, reassurance seeking, perfectionism or social withdrawal.
31. Can Exam Anxiety Cause a Teenager to Go Blank?
Yes. High stress can interfere with concentration and working memory, making it difficult to retrieve information under pressure.
Read Exam Anxiety in Ireland.
32. What Treatment Is Best for Anxiety?
There is no single best treatment for everybody. Psychological therapy has strong evidence, and medication may be appropriate for some people. Clinical Hypnotherapy, Clinical Medical Hypnotherapy, RTT and Registered Nutritionist Services may be integrated where appropriate.
33. Can Counselling Help Anxiety?
Counselling can help identify triggers, understand emotional patterns, improve coping, reduce avoidance and work through relationship or life difficulties contributing to anxiety.
Learn more about Counselling and Psychotherapy.
34. Can Psychotherapy Help Panic Attacks?
Psychotherapy can help identify panic triggers, reduce catastrophic interpretation of sensations and address avoidance patterns.
35. Can Clinical Hypnotherapy Help Anxiety?
Clinical Hypnotherapy may form part of an individual treatment plan for anticipatory anxiety, physical tension, fear associations, sleep difficulties and habitual responses.
Learn more about Clinical Hypnotherapy in Ireland.
36. Can Clinical Hypnotherapy Help Panic Attacks?
It may be used alongside broader therapeutic work to address physical arousal, fear associations and anticipatory anxiety. Suitability should be assessed individually.
37. Can Clinical Medical Hypnotherapy Help Anxiety Linked with IBS or Medical Procedures?
Clinical Medical Hypnotherapy may be considered when anxiety interacts with digestive symptoms, chronic pain, medical procedures, needle fear, dental anxiety or anticipatory nausea.
38. Can Nutrition Help Anxiety?
Nutrition can influence energy, digestion, blood glucose, sleep and nutrient status.
Registered Nutritionist Services may be relevant where anxiety occurs alongside digestive problems, irregular eating, hormonal symptoms, fatigue or dietary restriction.
Learn more about Registered Nutritionist Services.
