Phobias are irrational, involuntary fears of specific places, objects, activities, or situations. Most people deal with phobias by avoiding the situation or object that causes them to feel panic (avoidance behavior). Phobias are a common anxiety-related disorder.

A phobic disorder occurs when the avoidance behavior becomes so extreme that it interferes with your ability to participate in your daily activities. There are three main types of phobic disorders:

• Fear of being alone or in public places where
  help might not be available or escape is impossible (agoraphobia)
• Fear of situations where the individual might be exposed to
  criticism by others (social phobia)
• Fear of specific things
  (specific phobia)
