Generalized Anxiety Disorder
Chronic, excessive worry or anxiety for a minimum of six months characterizes generalized anxiety disorder. One usually worries about a number of events or situations such as work, health, relationships, and money, and has a very difficult time trying to control the anxiety. Physical symptoms such as restlessness, fatigue, difficulty concentrating, sleep disturbances, and muscle tension occur during this time as well. Irritability is also a common complaint.
