Sure sounds like your doctor increased the Tapazole too much, too fast. I'd suggest that you get tested for the biologically active thyroid hormones, Free T3 and Free T4 (not the same as Total T3 and T4), in order to better understand your status. I expect that you will find your Free T3 and Free T4 to be very low in their ranges, which is frequently associated with being hypothyroid. Your meds need to be adjusted adequately to prevent having either hyper or hypo symptoms. You need to be euthyroid.
