Autoimmune disorders

I was diagnosed with Grave's disease in 1998. I have been sick for as long as I can remember. RAI totally wiped my thyroid out. I have sever diarrhea and unable to gain weight. I have dry skin and hair. I itch like mad all over all the time. I get rashes and hives. I get bruises for no known reason. I had ablation for sever menstrual bleeding several years ago. I have 3 kids and am just 34 years old. I have chronic pain, night sweats, nightmares. My blood sugar does strange things, but my endocrinologist told me its no issue since my A1c is normal. I am a registered nurse and am sick of physicians calling me a liar, ignoring me, and just not caring. I am sick. I have a family and a career to enjoy. I have not worked in 2 months due to the bowel issues having gotten worse. I am exhausted and rarely leave my bed. I have dealt with depression and am not depressed at this time. I just want help!
