FORGET the THS. FORGET the TSH. Go by your
T4 free and T3 free
T4 total and T3 total.
These endos are hung up on TSH. Get your levels up in the upper part of the ranges, especially T3 free. From your symptoms you are Hypothyroid and YES low Thy can cause low T.
I have gone through this for a long time. I will say it again, FORGET the TSH you have to go by how you feel and not the TSH number.
