I agree. If you're feeling tired, gaining weight, depressed, weepy...it COULD be a thyroid problem. My dd (just turned 18) has had a helluva go the past few years, and we finally found out...hypothyroid. They're calling it thyroiditis, which basically means they don't know WHY but it should resolve on its own. Could be, could not be...but there has been a major change in the past year since we're treating the thryoid, and not "depression" which hypothyroid mimics.
