GAD is a pervasive and frightening experience of worry and fear that is out of proportion to the situation at hand. One’s worries may get so out of control that a feeling of general anxiety can lead to a full blown panic attack. People who experience GAD may go on to be diagnosed with Panic Disorder and/or depression if their symptoms persist. Some of the most common symptoms of anxiety are excessive worry or apprehensive expectation that is difficult to control. People with anxiety may feel restless, keyed up or edgy. They may be easily tired and have difficulty concentrating. Someone suffering from anxiety may experience muscle tension and sleep disturbances. With generalized anxiety the worry and fear is not specific; one is not worried about having a panic attack, or being contaminated or gaining weight as in Anorexia Nervosa but the worry is present and is causing significant stress. Usually people suffering from GAD have impaired relationships, problems in their jobs and problems with their friends and families.
