Hi hun, wow going to school and raising 2 children. That would be hard on anyone even if they are healthy. I am on effexor for depression as well. really like it which is more then i can say for the rest of the anti depressants. Don't ya just love it when the doctors throw out opinions without even doing the tests? I mean if that was okay then why not just get out one of those little black 8 balls that say yes or no. Or my favorite is Check back later!
I can't tell you nor can anyone else here tel you what the problem is. I can tell you that you do have something going on. I don't know anything eczema butt I wouldn't think it would cause all of the other problems you listed. With the skin problem it's good you saw a derm. but for the other problems you really need to see a rheumatologist. I would recommend you call around and find one that knows about lupus and other autoimmune diseases. Some only treat things like arthritis. Also if you don't like them or they can't help you then you move on. Most of us have been to 3 or 4 different doctors before finding a good one. Then they end up moving or somthing. If you find a good one the chances are slim they will find out right away what you have. It could be months even years. The main thing is they treat your systems at this point. There are some pretty mild drugs they can give you to help with fatigue which are used for many autoimmune disease.
Please let us know what you find out. Hang in there. and welcome to the group!
