hello, i have been putting on weight slowly over the last few years, i am always tired and have suffered with anemia over the last four years my nails are very thin, as is my hair all my problems seem to indicate a thyroid problem but my doctor says my tsh level is ok, what could be wrong with me, i have been under extreme stress over the last six years, i was put on anti depressants that caused me panic attacks so i have stopped taking them. its all a bit confussing really but the weight is so upsetting and the tiredness is awful as im too tired to exercise, i can sleep 7 hours and wake up like i haven t slept !
