Agoraphobia
Agoraphobia is an anxiety disorder involving unrealistic fears in life situations where a person feels trapped and unable to get help if needed. Examples of such situations include open spaces (bridges, marketplaces, parking lots, highways), enclosed spaces (movie theaters, shops, lecture halls), crowds, and public transportation where escape would be difficult.
This is a fear-based disorder that can be incapacitating. Oftentimes, the individual fears the possibility of a panic attack or other embarrassing or frightening occurrence. The individual with this disorder actively avoids the situation that would prompt such fear and anxiety. This avoidance can become so severe that sufferers can be housebound for many years, unable to work or go to school, and relying on others for help in managing daily needs.
