Welcome to the WHL and you've joined a wonderful large family here, always ready to give support and help.
No your not going mad mate, i've suffered alot of your symptoms and i have manic depression and that's a well known nightmare on it's own never mind anything else. With everything your going through i am glad for you that your finally going to Rheumatology, i'm under them and still waiting more blood results and to hear about x-rays they've took besides being under the skin specialist as i'm suffering bad with my skin each year they're moving me onto something else.
With everything you've mentioned i'd definitely say you have it, so forget the attitude with other doctor's and what they think you are it's just that alot of them today don't want to genuinley help patients and pull their fingers out, it gets me so mad.
All the best Terri xxx
