Agoraphobia is an anxiety about being in places or situations from which the escape may be difficult or embarrassing (i.e., travelling in a car or a bus, crossing a bridge, being outside the home, being in a crowd, being in enclosed place, standing in line, etc.) In many cases, the person suffering from agoraphobia tries to avoid the feared situations or endures them with great distress. In severe forms, a person may become completely home bound. 

The treatment of choice of agoraphobia is Cognitive Behavioural Therapy (CBT). Treatment includes identifying and, if needed, modifying the thoughts that underlie and drive the person's fear. Additionally, it involves gradual step-by-step exposure to feared situations with the purpose of helping the person unlearn the conditioned fearful response. 

Most people with agoraphobia have other psychological conditions such as panic disorder, phobias, social anxiety, etc. It is very important to establish the correct diagnosis as it will guide the treatment.
