I have had stomach cramps, bloated stomach and diarrhea for a little over a week. ill go several days when i really cant eat a meal at all and then a day or two where i feel a bit better and eat a couple small meals. currently back to not eating?

Your symptoms are somewhat not consistent with the natural history of an acute gastroenteritis, either caused by viral or bacterial infection. However, one week is too early to jump into any conclusion. I would advise good hydration, somewhat selective in your foods and eat light diet for another week. If the overall symptoms do not improve after 2 weeks, see your doc for a basic work-up.
