About Generalized Anxiety Disorder
Generalized Anxiety Disorder is characterized by excessive worry, but such worries are distinguished from obsessions by the fact that the person experiences them as excessive concerns about real-life circumstances.
For example, an excessive concern that one may lose one’s job would constitute a worry, not an obsession. In contrast, the content of obsessions does not typically involve real-life problems, and the obsessions are experienced as inappropriate by the individual (e.g., the intrusive distressing idea that “God” is “dog” spelled backward).
