Generalised Anxiety Disorder: When Your Brain Will Not Stop Worrying
You worry about your health. You worry about money. You worry about your children, your parents, your relationship, your career, the state of the world, that one thing you said three years ago. The worry is not attached to any single catastrophe — it moves freely from topic to topic, lighting on whatever is available.
You know it is excessive. People tell you that you worry too much, and you agree with them. But knowing does not help. The worry is not a choice.
This is generalised anxiety disorder — and it affects far more people than recognise themselves in the diagnosis.
What Makes GAD Different
Most people worry. Worry is adaptive — it is the brain's way of anticipating problems and preparing for them. GAD is different not in the presence of worry but in its quality: the worry is uncontrollable, the worries are multiple and shifting, and the duration is chronic — persistent for more days than not, for at least six months.
People with GAD typically cannot identify a single source of their anxiety. They are not anxious about something specific, which is what makes it so difficult to explain to others ("But what are you actually worried about?") and so exhausting to live with. The anxiety is the medium, not the message.
Physical Dimensions of GAD
GAD is not only psychological. The chronic activation of the stress response produces real physical symptoms: muscle tension (particularly neck, shoulders, and jaw), fatigue, headaches, sleep disturbance, gastrointestinal problems, and irritability.
People with GAD often arrive at doctors' offices with physical complaints first. The anxiety may not be the presenting problem — the chronic tension headache is.
The Function of Worry
One of the counterintuitive insights from anxiety research is that worry serves a function. For many people, worry feels like problem-solving — a way of keeping control over a dangerous world. "If I think through all the bad things that could happen, I will be prepared."
Worry also suppresses the physical sensations of anxiety more effectively than relaxation does. This sounds paradoxical, but worry is a cognitive activity that keeps you in your head and out of your body. Some people prefer the mental activity of worry to the physical discomfort of the underlying anxiety.
Understanding why you worry — what it is providing — is part of effective treatment.
What Helps
CBT for GAD typically involves identifying and challenging worry thoughts, learning to tolerate uncertainty (which is the core trigger for much GAD), and reducing worry behaviours (behaviours that temporarily reduce anxiety but maintain the cycle long-term).
Mindfulness-based approaches — particularly MBSR and MBCT — have strong evidence for GAD. They target the relationship with worry thoughts rather than the content of the thoughts themselves.
Relaxation training and somatic work address the physical symptoms of chronic anxiety — muscle tension, shallow breathing, chronic activation of the stress response.
Medication — SSRIs and SNRIs — is effective for GAD and is often used in combination with therapy.
GAD is very treatable. With the right support, the worry that has organised your life can loosen its grip.
