I want to start with something I say to almost every patient I see for anxiety: what you are experiencing is not a sign that you are weak. It is not a sign that your faith is insufficient. It is not evidence that you cannot cope. It is a physiological response — your nervous system behaving in a specific, well-understood way — that has become miscalibrated.
I say this particularly for African and Black patients because the cultural narrative around mental health in many African communities still frames anxiety and depression as spiritual problems, as weakness, as something to be prayed away or simply endured. There is nothing wrong with prayer. But it should not come instead of understanding what is happening in your body and accessing the treatments that are known to work.
What anxiety actually is — the physiology
Anxiety is your threat-detection system — specifically, the amygdala (a small almond-shaped structure in your brain) — triggering a physiological response to perceived danger.
When the amygdala fires, it activates your sympathetic nervous system, releasing adrenaline and cortisol. Your heart rate increases. Your breathing becomes shallower. Your muscles tense. Blood flow redirects to your limbs. Your digestive system slows. Your focus narrows to the perceived threat.
This is the fight-or-flight response. It evolved to help you survive a predator. It is extremely effective for that purpose.
The problem is that in modern life, the amygdala can be triggered by things that are not actually life-threatening: a difficult email, a social situation, financial worry, health concerns, relationship tension. And in people with anxiety disorders, the amygdala fires too easily, too frequently, or in response to triggers that don't warrant that level of response.
The symptoms of anxiety — racing heart, tight chest, shallow breathing, dizziness, sweating, nausea — are not imagined. They are real physiological events.
Types of anxiety disorder
Anxiety is not a single condition. The main types:
| Type | Core feature |
|---|---|
| Generalised Anxiety Disorder (GAD) | Persistent, excessive worry about multiple areas of life |
| Panic disorder | Recurrent, unexpected panic attacks with fear of future attacks |
| Social anxiety disorder | Intense fear of social situations and being judged |
| Health anxiety | Persistent fear of having or developing serious illness |
| PTSD | Anxiety and intrusive symptoms following trauma |
| OCD | Obsessive thoughts and compulsive behaviours |
These are different conditions requiring somewhat different treatment approaches, though there is significant overlap in what helps.
Case study: Adaeze's panic attacks
Adaeze, 34, a nurse from Nigeria based in Manchester, came to see me after her third visit to A&E in two months with chest pain and difficulty breathing. Each time, her ECG and blood tests were normal. The A&E team told her it was anxiety. She did not believe them.
"I thought they were dismissing me," she told me. "I thought they hadn't found what was wrong."
This is extremely common. The physical symptoms of panic attacks — chest tightness, racing heart, dizziness, feeling of impending doom — are indistinguishable from those of a heart attack in the moment. The subjective experience is that something is catastrophically wrong.
I spent time with Adaeze explaining what was happening physiologically. That the symptoms were real. That they were caused by her nervous system, not her heart. That the response, while terrifying, was not dangerous.
We discussed the pattern — the attacks were coming in the evenings, after night shifts, when she was alone and tired. Sleep deprivation was significantly lowering her threshold. We worked on sleep hygiene first. Then I referred her for CBT.
She had 8 sessions of CBT. She has not been to A&E for anxiety in 18 months.
What actually works — the evidence
Cognitive Behavioural Therapy (CBT)
CBT is the most evidence-based psychological treatment for anxiety disorders. It works by identifying the thought patterns that maintain anxiety (cognitive) and changing the behaviours that reinforce it (behavioural). It is typically 6–20 sessions.
Evidence: multiple large randomised controlled trials show CBT is as effective as medication for most anxiety disorders, with more durable effects (benefits last after therapy ends, whereas anxiety often returns when medication is stopped).
Access: in the UK, you can self-refer to NHS Talking Therapies (formerly IAPT) without going through your GP. Go to talkingtherapies.nhs.uk and enter your postcode.
Medication
SSRIs (sertraline, fluoxetine, escitalopram) are the first-line medication for most anxiety disorders. They are antidepressants, yes — but in this context they are treating anxiety, not depression. The name is misleading. They work by increasing serotonin availability in the brain and typically take 4–6 weeks to work fully.
Beta-blockers (propranolol) block the physical symptoms of anxiety — racing heart, tremor, sweating — without sedation. They are used for situational anxiety (job interviews, presentations) rather than generalised anxiety.
Benzodiazepines (diazepam, lorazepam) are effective for short-term relief but are habit-forming and are not appropriate for long-term use. They should not be the primary treatment for chronic anxiety.
Exercise
The evidence for exercise as an anxiety treatment is genuinely strong. Regular aerobic exercise (150 minutes of moderate intensity per week — brisk walking counts) reduces anxiety through multiple mechanisms: reducing cortisol, increasing endorphins, improving sleep, and providing a sense of control and agency.
This is not a substitute for therapy or medication in moderate-severe anxiety. But it is a meaningful adjunct.
Breathing techniques
Slow, controlled breathing directly counteracts the physiological anxiety response by activating the parasympathetic nervous system. The 4-7-8 technique (inhale for 4 counts, hold for 7, exhale for 8) is one of several approaches with evidence behind it.
This will not cure anxiety disorder. But it can interrupt a panic attack in progress.
The stigma conversation
I see Black and African patients who have been anxious for years before seeking help. The barriers are real: cultural expectation to cope, religious frameworks that pathologise mental illness, fear of being seen as weak, family shame.
I want to say plainly: anxiety is a medical condition. Seeking treatment is not weakness — it is the same common sense that leads you to take blood pressure medication rather than just hoping your hypertension resolves.
You would not tell a diabetic patient to pray harder and push through. The same logic applies here.
