@a2dc2dc Good morning. Sounds like you’re having a very difficult and confusing time. I do agree with @gingerw about keeping a journal very day—it can really help. You sound just like me 2 years ago: confused, nauseated, hair falling out, weight loss, unable to walk without help. It was awful . After an MRI puzzled the local doctors, my husband took me to the university medical center. I was diagnosed with an autoimmune disease. Many rheumatologists are knowledgeable about autoimmune, so you might want to add them to your list of who to see.
Have the people around you noticed any changes in you? Is there someone you can talk with?
