Just that really. Is really getting me down. I take 150 levothyroxime a day, blood levels have improved but I cannot lose weight. Have about three stone to lose and finding so hard. Admit lack of energy makes exercise hard but I don't massively overeat - by this i mean diet could be better but not horrendous. I was a small 12 ish before I put on in very short space of time so now 18 and I don't feel myself, am really down about it. Any tips would really be appreciated!
