Pissed off at people who ruined my friendship

So I was trying to become friends with this girl and it went pretty well like we got along and had lunch and stuff but some of the people I knew would trade me Infront of her or something like that and later when she stopped coming to class and stuff, i feared that she stopped talking to me so she wouldn’t get teased as well or that she thought I liked her which I didn’t. Idk I’m Soo pissed at them for teasing me and causing my friendship to break down
