Feeling abnormally illl?

Hello. Sounds like you have a stomach bug. There's really not much you an do, except wait for it to run its course. That can take a week to 10 days. You should only be eating bland foods like soup, toast, crackers, pudding, applesauce, etc. Eating foods like lasagna and McDonalds probably just made things worse. Eat light, drink lots of fluids, get some rest, and i'm sure you'll be feeling better in no time. Take care.
