Hi Dorma,
I'm so sorry you are having such awful problems! Not being able to eat and only 84 pounds! And the doctors not seeming to care or do anything about your situation! If you feel good enough, look up all of your medications and their side effects to see if any of the side effects are affecting your nausea and appetite and weight loss. Do the search on the Mayo Clinic. That way, you'll know that the information you get is correct.

One thing that can cause you to lose weight is incontinence. I know because I am incontinent and went from a size 12 slacks down to a size 6!

I think at this point it would also be a good idea to just talk to God and give him all your problems and let him fix them. He made you and he can fix you! You don't have to go to church to find God, although churches are very nice. Just talk to God like he's your best friend and he is! I'll say a prayer for you also.
I wish you the best,
PML
