Most importantly you have an accurate diagnosis and are on appropriate treatment. Now you could benefit from stress management coaching by a mental health professional. This cognitive treatment will help you to cope with your illness and allay your marked anxiety about it. Getting reassurance about your cardiac status(if necessarily from a cardiologist) is very important, also.
