Hi, Patricia! I hope things go well for you at your doctor's appt, and that you get a diagnosis. I had an overactive thyroid as an adolescent, which was not positively diagnosed until I was 21, when I had a thyroid storm, and subsequently had a goiter and partial thyroidectomy. But I remember suffering for years from the effects of an overactive thyroid, and the doctors knew something was wrong, but couldn't figure out what it was. I see from your post you've already spent 6 years trying to get a diagnosis!!!!
Hugs, Lois
