please check out this link, it will explain alot about how your thyroid works and how tsh can be very good and your t3 or t4 can be way way off and is why you may be having symptoms. Alot of doctors simply have no training in how the thyroid works.
I hope this works for you. And I hope you feel better.
Warmest of Regards
