Farted at school. Wishin I was dead. Don't want to go back. What now?

Today in Mr. Rogers science cl me an Jonathan an Calvin an Jeff was havin lots a fun an laughin an jokin an stuff. Jonathan told a funny joke an we was all laughin an I farted! It was loud an really smelly an I was SO EMBAREED. People was flappin there arms an gaggin an stuff an then Jonathan said "Jesus Christ Franklin did you crap you're pants or what?" Then EVERY ONE new it was me that farted. Mike an Willy said it stunk real bad an that I was a stupid an then Jackie an Ernie said they would kick my *** after school for stinkin up the room. :'( I was so scared I didn't ride the bus home cause they ride the same bus an I had mommy come an pick me up at school. Now I'm scared to go back cause I don't want to get beat up over accidental farting. What can I do? I'm 15, am I old enough to quit school now?
