It sounds like you may also have gastrointestinal issues. Have you been to see a good GI doc? And make that appointment yesterday if you are detecting any blood in your stools. I lost 40lbs in one month from acute ulcerative colitis. Required a week of TPN before they could do surgery, I was so weak and malnourished.

Take care. If you have a GI diagnosis, it might help. I was accepted on my second try.
