Very frustrating: Anxiety disorders are often quite varied and can respond to medications and counseling. Sometimes it can take a while to find the best medications. If cardiac symptoms are present they should be checked out, although uncommon at your age. Go over your history and symptoms with your medical provider and if you do not get improvement consider seeing a specialist such as a psychiatrist. Good Luck!
