Autoimmune disease: You should see an endocrinologist to accurately diagnose your condition. More than one autoimmune condition could be present, so diagnosis and treatment have to be correct. The combination of thyroid, adrenal, and hematologic disorders is potentially serious and complex.

See a doctor: You should see a doctor so that they can give a proper diagnosis and prescribe you some medications that will help you.

Big picture: Cannot diagnose you in one paragraph. I would have to do a major work up. But possiblities include an infection such as lyme, toxicity of some kind including heavy metals, micronutrient deficiencies, etc. There is likely more than one thing going on. See a good endocrinologist if you have not done so yet.
