I have been feeling a bit sick can someone help?

Well it started when I ate carne esata chips.. I think that's how is spelled... Well it was good then later a night I started feeling bad.. I did think some sodas though.. It felt like I was going to vomit but I never did... So the next day I still felt it but it wasn't as bad so on and off the day it felt more bad ( but never as bad as the first feeling) just bothers me a little... And at night it may have hurt my stomach a bit ( at night I feel worse as I am going to die or something bad will haopen ) idk why iv always been like that after the day my bro made me take 12 different type of pills I puked all night) but anyways it is about 2 days later or 3 and I still feel a tiny bit bad and it bothers me so I can't sleep much... When I use the bathroom not in the fecies but floating is something white and clear with some fecies on it floating... Is that normal wIth Mexican food and soda eating fast? Or am I sick do I got worms or food posioning? I would like a helpful awnser though... Thanks
