This is just a thought. I've suffered from what I thought was just depression. Had other physical symptoms that I attributed to other things. Came down with diabetes and the doctor did labs before he put me on an oral medication. Liver enzymes were elevated. A year later, I asked my new doctor about the elevated enzymes. He repeated the liver panel and then referred me to a GI doctor, whom then ran a bunch of lab test, that I would've never thought of, and had many abnormals. Then on to the rheumatologist after my regular doctor said the labs suggested Lupus. Finally ended up with a diagnosis of Sjogren's syndrome, an autoimmune disease, in which there are few clear symptoms, the possibility of having other diseases along with it, such as lupus, rheumatoid arthritis, etc. It now makes some sense. The depression, anxiety, fevers, joint pain and generally not feeling all that good. Most of the time I couldn't and still can't pinpoint specific symptoms when I don't feel good. It's just a thought. Remember, doctors are human beings who want to help, but there are so many diseases out there that are similar, it's hard to diagnose them properly.
