I'm in sophmore year, and I'm 16M. Over a year ago, I liked a girl (For the sake of the story, let's call her Emma). My other friend Anna who was her best friend promised to set us up. However, I never asked Emma out, and me and Emma fell out of touch. Mind you, I only liked her for max 1 week. Come now, over a year later, and I am friends with most of Emma's friend group (mainly Anna, Jesse, and Camila). Me and Anna and Jesse have plans to hang out on Friday just after school (just walk to safeway and perhaps go to one of Anna's house). Then out of nowhere, Emma dms me on insta and I quote direct here, "Dude uhm don’t come with us on Friday cause it’s galetines and your not a gal thank you." I'm sad and annoyed because she was never part of the original plan and I didn't even know she was going to come, but sure. I'm a little bit at Anna and Jesse but overall I was fine. Then out of nowhere, on thursday, I hear that Emma was shit talking me for the last year, and apparently told Jesse when they were first starting to be friends (I knew Jesse before Emma) that I asked her out 5 times, was creepy, and if I was friends with Jesse, would ask her out. And then it all exploded on Thursday when I hear from my friends who are in Precalc with Emma and Camila that they were straight up yelling at each other about how creepy, ugly as fuck, and overall "bad" I was and even ranted to the teacher about it. According to all 3 of my friends, they were so loud that the whole class heard them, and they even name dropped me, and my reputation (which is already not particularly good) was basically shit now. I had to talk with Jesse (who was also in the Precalc class, but was not involved in the shit talking) to try and fix my reputation and to tell Emma and Camila to keep my name out of their mouth, and to clear my reputation with the teacher and the rest of the class, but now I'm worried because I don't know how many people Emma shit talked me to, and I genuinely could get jumped, and overall I'm really lost on what to do. I also don't think Jesse did much to help fix it because from what I've heard, she just told the teacher (and the class) that it was "resolved," and I'm genuinely so lost on what to do. Literally any advice would help me right now because I am in tears cause I didn't do any of that
