The peak generally lasts for 5-10 minutes, but it can take much longer for all the anxiety to subside.

Panic disorder with agoraphobia is anxiety about being in places or situations for fear of having a panic attack or panicky feelings and that they will not be able to escape. Situations may include being away from home, queuing, travelling on public transport or using lifts. Some people avoid these situations completely. Others force themselves into feared situations, but feel anxious and panicky throughout.
