Im so sorry you dont get support from your mother. I know how hard it can be when family aren't supportive. Im 19 and have hypothyroidism and my family is quite unsupportive, it does get hard when you need that suppport and it isnt there - I know that feeling all too well.
Try to keep positive and hopefully the dr will find the perfect medication for you and you will feel better and more like yourself.
Take care, Nat
The first thing I want to tell you is that T3 med does NOT convert the T4; T3 med is just that T3; it will raise the FT3 levels in your blood, but does nothing to the T4.
I'm very sorry that your mother is so unsupportive. You are right, this is a hard disease to live with, but as time goes by, you should start feeling better; then hopefully things won't look so bleak.
Take care.
Barb.
