What's going on?

[Jaygirl007]

So Christmas Eve I woke up just feeling nauseous. And I kinda felt light headed. Well I got up. Went to the bathroom. Went and sat on my couch and blacked out for a second then I was fine, about 10 minutes later I threw up. Nothing more than phlegm.

Well later on that day I got to feeling muscle aches and hurting. And just fever and the usual stuff. So I suggested the stomach bug. And I ate a very small amount. And about an hour and a half later I puked again. And still nothing but phlegm. The next morning I woke up feeling nauseous still but nothing but diarrhea.

Monday I was semi okay, but when I got to moving I felt pressure and in my gallbladder area like I did the other times I puked. But I never did. Just got real sick and light headed and almost fainted. And today is Tuesday and I'm still getting this randomly through out the day with small spurts of diarrhea. But no more vomiting. Just strong feelings like I am. After I eat since I haven't ate in days.

Would this be the stomach bug? My gallbladder? My appendix? Etc?

Help meeee.
