Hi ZebraChat and
Though the doctors have to do the diagnosing and we're not medical doctors, you'll find quite a few people here who understand the misery of having to wonder what is going wrong and not having an answer.
Back when I was in diagnosis limbo, which went on for several years, I had good days when I decided I was just having problems with stress, or maybe it was just a slipped disc. Then I had not-so-good days when I was thinking in terms of a tumor.
I hope that your problems will turn out to be due to something treatable.
