Nobody has ever come to me and said I think I have an anxiety disorder. They come because they cannot sleep. Because their heart races on the Tube for no reason. Because they have avoided their email inbox for three days and cannot explain why. Because they had to leave a supermarket in a hurry, convinced something was wrong with their heart, and felt embarrassed about it for a week afterwards.
Anxiety disguises itself. It calls itself stress, overthinking, being sensitive, not coping well. In African and Caribbean communities specifically, it often gets labelled as laziness or lack of faith - and those labels are far more damaging than the condition itself, because they replace a medical explanation with a moral one.
Here is the medical explanation, plainly: anxiety is your nervous system behaving in a well-understood, measurable, physiological way. It has identifiable mechanisms. It responds to specific treatments. And it is not - not even a little bit - a reflection of your strength, your character, or the depth of your faith.
What anxiety actually is - the physiology
Anxiety is an activation of your sympathetic nervous system - the fight-or-flight response that evolved to protect you from immediate physical danger. When your brain perceives threat, it triggers a cascade: the hypothalamus signals the adrenal glands to release adrenaline and cortisol. Heart rate increases. Breathing quickens and becomes shallower. Muscles tense. Blood glucose rises to provide energy. Digestion slows. Blood flows to the large muscle groups and away from the digestive tract and skin.
This response is extraordinarily useful when the threat is a lion. It becomes a problem when the threat is a presentation at work, a difficult conversation, a piece of mail you have not opened, or a memory of something painful - situations where the physiological response is disproportionate to the actual danger and where running or fighting are not appropriate responses.
In anxiety disorders, this system is activated too readily, too intensely, or too persistently. The alarm is calibrated too sensitively. It fires when it should not, or keeps firing long after the threat has passed, because the brain has learned to perceive certain situations or sensations as dangerous when they are not.
Types of anxiety disorders
Generalised Anxiety Disorder (GAD): Persistent, excessive worry about multiple areas of life - work, health, finances, relationships, the future - that the person finds difficult to control. The worry is acknowledged as disproportionate but cannot be stopped by willpower. Physical symptoms include muscle tension, fatigue, sleep disturbance, difficulty concentrating, and irritability. GAD is the most common anxiety disorder in adults.
Panic Disorder: Recurrent, unexpected panic attacks - sudden surges of intense fear that peak within minutes, with physical symptoms so severe they frequently lead people to A&E convinced they are having a heart attack: chest pain or tightness, racing heart, shortness of breath, dizziness, tingling in hands and face, feeling of unreality, fear of dying or losing control. Panic attacks are not dangerous. The physical sensations are real and alarming, but they are caused by the fight-or-flight response, not by cardiac or neurological disease. After repeated attacks, people develop anticipatory anxiety about having further attacks, which itself triggers more attacks.
Social Anxiety Disorder: Intense, persistent fear of social situations in which the person might be scrutinised, judged, or humiliated. Goes well beyond ordinary shyness. Causes significant impairment in work, education, and relationships. People with social anxiety often avoid situations that most people take for granted - eating in public, speaking in meetings, making phone calls.
Health Anxiety (Illness Anxiety): Persistent, excessive preoccupation with having or developing a serious illness. Reassurance - from doctors or from internet searches - provides only brief relief before anxiety returns. Paradoxically, repeated medical consultations often worsen health anxiety by reinforcing the idea that something is wrong.
Specific Phobias: Intense, irrational fear of specific objects or situations - spiders, needles, blood, flying, vomiting, dogs. The person recognises the fear as disproportionate but cannot control it through reason. Highly treatable with exposure therapy.
Case study: Adaeze's panic attacks
Adaeze, 34, a secondary school teacher from Nigeria based in Manchester, came to see me after her third visit to A&E in six months. Each time she had presented with chest tightness, heart racing, shortness of breath, and overwhelming terror. Each time, her ECG was normal, her troponin was negative, and she was discharged with reassurance.
She was not reassured. Between A&E visits, she had started checking her pulse multiple times per day. She had stopped exercising because she feared exertion would trigger another episode. She had reduced her teaching timetable because the classroom - the noise, the unpredictability - felt dangerous. She had stopped going to church because she feared having an attack in public.
When I took a full history, the clinical picture emerged clearly. Her first episode had occurred the morning after an especially difficult parents' evening. Subsequent episodes were tightly clustered around workplace stress. She was sleeping 4-5 hours per night. She had lost 5kg.
She had panic disorder with health anxiety secondary to it. Not a cardiac condition.
I explained the physiology in detail. I drew the vicious cycle on a piece of paper: hyperventilation from anxiety causes physical symptoms (tingling, chest tightness, dizziness) which are interpreted as dangerous, which increases anxiety, which increases hyperventilation, which worsens symptoms. I explained that her heart was fine. I explained that avoidance was making the panic disorder worse, not better - that every time she avoided a situation she associated with panic, she confirmed to her nervous system that the situation was dangerous.
I referred her for CBT. Twelve weeks, 12 sessions.
Four months after I first saw her, she had not had a single A&E attendance. She had returned to full teaching hours. She had started running three times a week.
"I cannot believe I spent a year convinced I was dying," she told me. "Nobody had explained what was actually happening in my body."
What actually works - the evidence
Cognitive Behavioural Therapy (CBT): The most evidence-supported psychological treatment for all anxiety disorders. The fundamental principle: anxiety is maintained by avoidance and by catastrophic interpretations of threatening situations. CBT addresses both - through cognitive restructuring (examining and challenging anxious thoughts) and through graded exposure (gradually approaching feared situations or sensations, rather than avoiding them).
For panic disorder, a critical component is interoceptive exposure: deliberately inducing the physical sensations of panic (through spinning, hyperventilating, or running on the spot) in a safe environment, to learn that these sensations are uncomfortable but not dangerous.
CBT for anxiety typically involves 12-20 sessions. Access through NHS Talking Therapies (self-refer at talkingtherapies.nhs.uk, no GP referral required). Waiting times are typically 4-12 weeks. In the interim, Anxiety UK's helpline (03444 775 774) provides support.
Medication:
SSRIs (sertraline, escitalopram, paroxetine) are first-line medication for most anxiety disorders. They require 4-6 weeks to reach full effect. They are not addictive. They work best in combination with CBT rather than as a standalone treatment.
Beta-blockers (propranolol) reduce the physical symptoms of anxiety - heart rate, tremor - and are useful for situational anxiety such as public speaking or performance. They address the symptoms but not the underlying anxiety.
Benzodiazepines (diazepam) work rapidly but are appropriate only for short-term crisis use due to tolerance and dependency. They should not be used as ongoing anxiety treatment.
What does not help long-term: Avoidance is the main thing that maintains anxiety. Every time you avoid a feared situation, the anxiety about it increases. Alcohol reduces anxiety in the short term and reliably worsens it in the medium term. Reassurance-seeking (repeatedly checking, asking for reassurance, repeated medical consultations) maintains health anxiety.
Anxiety in African communities - the specific barriers
The barriers to recognising and treating anxiety in African communities are real and worth naming directly.
Stigma: Mental health problems are frequently attributed to spiritual causes or personal weakness in many African cultural contexts. The concept of anxiety as a medical condition that warrants professional treatment may feel foreign or even offensive.
Language: African languages often do not have direct equivalents for clinical terms like anxiety disorder or panic attack. Distress is more commonly expressed through physical symptoms - chest pain, heart racing, headaches, stomach problems. Presenting to a GP with physical symptoms and receiving a mental health diagnosis can feel dismissive of real suffering.
Fear of judgement: Within tight-knit African communities, seeking mental health help may feel like a risk to reputation - for oneself and one's family.
Distrust of services: Historical and ongoing experiences of discrimination within healthcare create legitimate reasons to be cautious about how distress will be received and interpreted.
These barriers are not insurmountable. Talking to a pastor, imam, or community elder is not incompatible with also seeking medical help. Prayer and evidence-based psychological treatment are not mutually exclusive. The goal is getting better - and both approaches can be part of the same journey.
