Anxiety

Anxiety is a normal reaction to stress. It can help you cope with a hard situation. For example, anxiety helps one deal with a deadline at the office or can push you to study for a test. But when anxiety becomes an extreme, irrational dread of everyday situations, it can be disabling. Anxiety disorders include:

• Generalized anxiety disorder
• Obsessive compulsive disorder
• Panic disorder
• Social phobia (or social anxiety disorder)
• Specific phobias
