Anxiety is a perfectly normal and often helpful feeling.
It prepares you for action and readies you to respond to a threatening situation. But when you are unable to cope with your fears to the extent that they disrupt your daily life, you probably suffer from an anxiety disorder. Anxiety disorders can cause overwhelming fear or the complete inability to deal with a given situation, for no apparent reason. Sometimes anxiety disorders can cause fear so intense it totally disables its victims. Anxiety disorders are the most common of all mental illnesses, and they are also the most treatable.
