“Anxiety” is a category, not a diagnosis. Underneath it are several conditions with different mechanisms, different treatments, and different timelines. A therapist who treats them all as the same thing — relaxation, coping strategies, talking it through — will help a bit and resolve none of them.
Generalized anxiety disorder
Chronic worry across many domains, drifting from topic to topic: money, health, the children, work, something you said in 2019. The physical signature is muscle tension, restlessness, fatigue and disturbed sleep.
The engine underneath is usually intolerance of uncertainty, and treatment aims there rather than at the individual worries. More on GAD.
Panic disorder
Sudden surges of intense fear with heavy physical symptoms — racing heart, breathlessness, chest tightness, dizziness, a sense of unreality — peaking within minutes.
The defining feature isn’t the attacks but what follows: fear of the next one.The fear of fear is the actual disorder, and the treatment —interoceptive exposure — is one of the most effective and strangest-sounding in the field.
Social anxiety disorder
Fear of being evaluated and found wanting. Not shyness — a conviction that you’re being scrutinised and are failing the test, with avoidance of the situations where that could happen.
Distinctive features include the two-hour replay afterwards and heavy self-focused attention during. More on social anxiety.
Specific phobia
Intense fear of one thing: flying, driving, needles, heights, dogs, vomiting. Narrow, sharply defined, and the most treatable condition in this whole field — often in a handful of sessions, sometimes one.
Agoraphobia
Fear of situations where escape would be difficult or help unavailable, typically developing out of panic. It rarely starts with open spaces; it starts with one cancelled plan.
Health anxiety
Preoccupation with having or developing a serious illness, maintained by checking, searching and reassurance. More here.
The ones that aren’t anxiety disorders
OCD was moved out of the anxiety category in DSM-5, and the treatments genuinely diverge: examining a worry helps in anxiety and feeds the loop in OCD. The distinction is here, and if it’s OCD, the treatment is exposure and response prevention specifically — see Online OCD Therapy.
PTSD also sits outside the anxiety chapter. When the alarm is a memory rather than a prediction, the treatment changes.
Why the label matters
Because the protocols differ. Panic needs interoceptive exposure. Social anxiety needs behavioural experiments and attention training. GAD needs uncertainty tolerance. Phobia needs graded exposure and usually little else. OCD needs response prevention.
Generic anxiety management helps all of them slightly and resolves none of them, which is why so many people conclude therapy doesn’t work when what they had was the wrong one.
