I am glad that you have been persistent in getting yourself evaluated by a physician. I am not a physician but a psychologist. I would recommend that you continue to speak with your physician to determine if there is something medically going on that requires your and your physician's attention. Since your physician has "put it down to stress until now" have you consulted with a licensed mental health professional? Even if your symptoms are not stress related your symptoms sound like they could be contributing to an increase in stress in your life. A licensed mental health professional may be able to help you identify some effective strategies that may benefit you while you get this sorted out medically and get re-engaged in your day to day life.

Best wishes to you.
