The fear is out of proportion to the actual situation and lasts generally six months or more and causes problems in functioning. A person with agoraphobia experiences this fear in two or more of the following situations: Using public transportation Being in open spaces Being in enclosed places Standing in line or being in a crowd Being outside the home alone The individual actively avoids the situation, requires a companion or endures with intense fear or anxiety. Untreated agoraphobia can become so serious that a person may be unable to leave the house. A person can only be diagnosed with agoraphobia if the fear is intensely upsetting, or if it significantly interferes with normal daily activities.
