sicker or more sick

I've never been more sick in my life. Or is it, I've never been sicker in my life? I have puked more and had more diarrhea than I care to remember in the past three days. I've lost 5 lbs and am down to 96 lbs total. I had to take my rings off because they were falling off my fingers. I have held down 2 peices of toast today and I'm praying they stick. I am soooooo hungry and having day dreams of a plain baked potato. Is this a good idea? This illness has me scared silly. I really have never been like this before and it keeps going on and on and on.... Somebody please help me!
