Get a physical exam. Give your doctor all of your personal history so that other conditions can be ruled out. Describe your anxiety symptoms in detail. Your doctor may also administer various screening tests to help diagnose anxiety disorder.
Get treatment. Most anxiety disorders respond well to treatment, although for some it may mean long-term therapy or medications. Most doctors will start your treatment with therapy and perhaps an antidepressant. Commit yourself to a healthy lifestyle including a good diet, exercise and rest. You may need to eliminate caffeine or other medications and supplements that worsen your anxiety.
Face your anxiety head-on. Don't fight your anxiety, but instead become detached and study it. Act as if you are not anxious. Know what triggers it and realize that there will probably always be some anxiety in the future--but now you are in control, not the disorder. Try to change your mindset so that the anxiety no longer dictates how you think and feel. When you accept your anxiety, you are now one step closer to taking your life back.
