Why does my stomach hurt?

Well its 1am and today i ate junk food all day and and i did no exercise. I ate kitkat. Reeses. Laffy taffy. Snickers. Hersheys. And warchamacallit. And when i came home i ate about 8-9 hot wingsand then one chicken burger. And i went to sleep. So im 15 and 4'9 and about 85 pounds. Is this bad? I think i just had a major pig out session and my stomach doesnt really hurt, but its hurting because im starting to feel that i ate a crap load too much..
