What is a Phobia?
A Phobia is an irrational fear and avoidance of an object or situation. Phobias are different from generalized anxiety disorders because a phobia has a fear response identified with a specific cause. The fear may be acknowledged as irrational or unnecessary, but the person is still unable to control the anxiety that results. Stimuli for phobia may be as varied as situations, animals, or everyday objects. For example, agoraphobia occurs when one avoids a place or situation to avoid an anxiety or panic attack. Agoraphobics will situate themselves so that escape will not be difficult or embarrassing, and they will change their behavior to reduce anxiety about being able to escape.
