Everyone experiences anxiety. Speaking in front of a group makes most of us anxious, but that motivates us to prepare and do well. Driving in heavy traffic is a common source of anxiety, but it keeps us alert and cautious to better avoid accidents. However, when feelings of intense fear and distress are overwhelming and prevent us from doing everyday things, an anxiety disorder may be the cause. Anxiety disorders are the most common mental health concern in the United States. An estimated 40 million adults in the U.S., or 18%, have an anxiety disorder. Approximately 8% of children and teenagers experience the negative impact of an anxiety disorder at school and at home. Most people develop symptoms of anxiety disorders before age 21 and women are 60% more likely to be diagnosed with an anxiety disorder than men.
