I have just seen a Lovely Doctor privately and what a difference.
I had plenty of time to tell him how I am feeling and ask all of my many questions and he really listened! He has increased my dose of levothyroxine from 25mcg to 50mcg as my GP had refused to once I was 'in range'. If I don't feel better I can return in a couple of months and be reviewed or e-mail him before then.
It has been a massive help to read everyones posts on here and I have been in touch with another member who was able to tell me about this doctor. Funny enough we even met up today by chance as my appointment followed hers!
To everyone still struggling, hang on in there, I know its horrendous but do keep going. If anyone would like this doctors details please private message me as I don't think I can put it on my post. Thank you to all the admins of this site, the information and support you give is invaluable.
