Please help me what should i do?

I was in schoool and i was in math B1 (9th grade) and i was having really bad stomach problems. I was sitting in my chair squirming around because i was having to poop really bad and im pretty sure people around me saw me and knew and they probably heard and smelled the constant farts that were slappin out of my butthole. my god those farts were awful i almost threw up because it smelled like a skunk crawled out of the butthole of another dead skunk. I was raising my hand after a little bit because i knew i couldnt hold it but the teacher was at his desk not looking at me. eventually i had to sneeze and when i did my butthole erupted in a endless flow of chunky diarrhea. i couldnt hold back from the force of my sneeze. it was really warm in my pants and uncumfortable and i was so scared someone would notice. eventually i felt sum on my leg because it was so much it started drippin down the leg of me and my chair and it formed a small little puddle on the floor and it was really weird looking i must have eaten something weird like my god it looked like if you mixed chili with applsauce and soup. it smelled like it too. Everyone around noticed and a few girls started yelling ewwwww so everyone in the class go up to look what was happening. the tool softmores of the class yelled "Hey guys look, smith is takin a dump in his chair!" then the teacher got up and told me to go to the bathroom. I got up and i was crying at this point and i waddled out of the room and to the bathroom and people saw me on the way i hope they didnt know i pooped my pants. i cleaned up the best i could in the bathroom and when i walked past the bathroom to go to the office i saw the teahcer cleaning up my poop with napkins but then he realized that was a bad idea so he called the janitor. I got picked up after that but my mom had to work so i didnt get to talk to her so ive been home alone since then. I was already kind of a loser in school and i get bullied a little bit for being fat ugly smelly and annoying but i do my best to ignore them. what should i do?
