The feared object/situation is avoided or endured with intense anxiety or distress. The avoidance, anticipation of, or distress of the phobic object/situation must cause significant distress or interferes with the individual's daily life, occupational, academic, or social functioning to meet diagnosis. The symptoms cannot be better accounted for by another mental disorder or be caused by substances, medications, or medical illness.
Simply put - agoraphobia means that you avoid a lot of ordinary activities and situations for fear of having panic attacks. To most people who get this diagnosis, the term sounds pretty scary, but that's all it means. It does not mean you are or will become house bound. That can happen to people, and is an extremely severe case of agoraphobia, but the great majority of people with agoraphobia do not experience it to that extent.
Because there are many medical conditions that can cause anxiety attack signs and symptoms, such as the strong sensations and feelings associated with anxiety attacks, it’s wise to discuss them with your doctor. If your doctor has attributed your anxiety attacks to stress and anxiety, you can feel confident that your doctor’s diagnosis is correct. Anxiety attacks and their signs and symptoms are relatively easy to diagnose and aren’t easily confused with other medical conditions.
