Agoraphobia is a serious type of anxiety disorder characterized by an irrational and overwhelming fear of being trapped or unable to escape a particular place. Agoraphobia can trigger intense fear and anxiety in situations where escape might be difficult or help unavailable. Common examples of situations or places that cause fear and anxiety include waiting in line at a bank or supermarket checkout, sitting in the middle of a long row in a theater or classroom, and using public transportation such as buses or airplanes.

Situations that may trigger fear in individuals with agoraphobia include:

Crowds or enclosed spaces
Open and expansive spaces
Being away from home
