How do you define generalized anxiety disorder?

Overanxious: This is considered to be an inherited tendency to be overly anxious, worry excessively, feel tense, and have difficulty dealing with every day stress. The mind may race with worries at nightt, leading to insomnia. Physical problems may be induced by the anxiety such as headaches, upset stomach, etc. Effective treatment is available such as cognitive psychotherapy and meds such as ssri's, benzos.

Unwarranted worrying: Generalized anxiety disorder (gad) refers to people who worry about lots and lots of things rather than specific things such as flying or insects. They feel worried, tense, and irritable more often than not beyond what is warranted objectively, with symptoms such as restlessness, poor conentration, and poor sleep. Some physical illnesses can cause gad but typically there is no known cause.
