I'm also hypothyroid. Had to argue with my doctor to get tested as I'm too "young" and "should" be tired with medical school. Finally got started on levothyroxine, took a number of months to get straightened out with the lab values, and I'm still not perfect (some tiredness and cold intolerance but no more menstrual problems and hair not falling out, and my energy is better and I'm not quite as cold). Don't expect results overnight - it'll take a few months of labs and med changes, but after a while you'll notice - hey! I feel better. Keep after it - i'm glad they found a reason for your problems. PM me if you have any questions. Good luck!!
