Another type of depression is a panic disorder. People who suffer from a panic disorder will have frequent panic attacks that cause them to have an overwhelming and unnatural fear that they are in some type of danger. During a panic attack these people may experience certain types of phobias that include a specific phobia to a certain condition, social phobia, or agoraphobia. All of these phobias are an unnatural, uncontrollable, and most times unstoppable fear of a certain situation, object, or action. People that have this type of anxiety disorder will go to any length to avoid the source of their phobia.
