Anxiety disorders are the most common psychiatric illnesses. An estimated 40 million American adults suffer from anxiety disorders. Even though the disorders are highly treatable, it is estimated that less than 1/3 of those affected seek out treatment.
While it is completely normal to experience occasional anxiety, some people experience an overwhelming amount of anxiety that may seem to be uncontrollable and irrational. When the level of anxiety a person experiences interferes with daily life, and routine activities, it may be an anxiety disorder and require proper treatment.
