It sounds like you have a good rheumy and I am happy for you. So many of them are not knowledgeable enough about lupus or ignore their patients concerns.
I read your first post and wanted to tell you I also deal with anorexia. It is awful and not easy to overcome. I was not anorexic when my lupus was discovered; I had protein in my urine also and my kidney biopsy showed lupus. I was shocked because I really didn't feel sick.
Let us know how you make out with your 24 hour urine and try to take care of yourself. I am much older than you but I do undertand what you are dealing with. Take care and enjoy college!
