AITAH for punching a guy in my class?
I (15f) have always been chubby. It's something im insecure about but learned to live with. I've got friends in my class who are super nice to me and make my day better. Now here's the problem. Today, a guy in my class, one of these classic gym jerks who has a whole list of demands for a future gf- was messing with me jokingly, and then suddenly called me a cow. The class was dead quiet and everyone was looking at us in pure shock. I usually don't lose my composure but seeing him embarrassing me in front of everyone, I lost it. I got on his table and slapped him a few times , kinda just beat him up. This was the first time I've ever lost my composure in school and I'm so freaking embarrassed. A few girls in my class were cheering me on and saying he deserves it but idk, I feel like I shouldn't have resorted to violence, embarrassment or not. Later a few people came to check up on me and told the guy he crossed the line, his best friend also walked me home and cheered me up, but idk I just feel so shitty for losing it in front of everyone and resorting to violence. So, AITAH?
