Generalized Anxiety Disorder is characterized by persistent and excessive worry. An individual’s fears can center on a number of different issues such as healthy, safety, finances, or a general feeling of impending doom. These worries are difficult to control and can appear irrational or an overreaction to the outside world. In addition to excessive worry, symptoms can also include restlessness, irritability, headaches, nausea, difficulty concentrating, muscle tension and being easily startled. Individuals with GAD tend to be very hard on themselves and strive for perfection. There is a tendency to seek reassurance and validation from others.
