Experiencing anxiety occasionally is normal. Anxiety may arise when problems confront us, prior to a test, or when making a life-altering choice. A disorder involving anxiety, though, is a far cry from temporary fear or worry. Overwhelming, persistent, and uncontrollable anxiety that interferes with relationships, school work, or job performance is cause for concern. Approximately 40 million of the adult, American population are afflicted by anxiety disorders, making them among the most common psychiatric illness in adults and children. Despite this prevalence and the fact that these disorders can be treated, only about one in three sufferers will get appropriate treatment.
