So I feel like I got food poisoning, or I tell everyone I do.

I went on vacation, and ate fast food for 9 days(not by choice, my aunt didn't cook). So now, I had my first homecooked meal last night.
Everytime I eat, my stomach hurts and all I wanna do is lay down and sleep.
Which it's making me go to bed earlier, which is bad since I have some homework to catchup on.
I need ways to get better.
I can't stand this feeling sick crap.
