Mentally Draining High School Politics

I'm losing it, I got framed and bad mouthed for 2 years in my previous school and had enough and transfered schools, but found out this school and the previous has some kind of connection so all those allegations and rumors are brought along to my current school. I transfered hoping to start off fresh just to be stuck with the same bullshit again in a different concrete building. The rumors and all are just that bad because previously I was framed by my ex gf for sexually assaulting her, I'm a guy therefore it's pretty much impossible to prove them wrong. But in this new school of mine the new allegations are me being mysogynist because a few girls had huge beef with me and now my reputation is heavily ruined.

It's honestly intimidating to see all the girls just whispering to each other when they communicate, especially when they are gathered up in HUGE groups like its a whole business meeting or something. And its sad to know that everyone in high school is just extremely two faced, you never know who's being real with you or planning to stab you in the back in the future. Pissing off the popular guys or girls would be game over for you if you status doesn't match theirs, I'm talking about students that teachers love and very proud of and not even teachers would listen to you because they think their student is just too good of a kid to do such a thing.

If I complain to my parents and they go to the teacher, they're just gonna trust the teachers that I am the one who initiated the conflict and I'm just being a dramatic child. "Talk to a trusted adult or guardian" they say, unfortunately even that option is gone for me.

Anyone here who is good at manuveuring in high school can give me some advice about picking myself up from the ground and possibly build up an "arsenal" to defend myself against those popular top students in high school? I'm honestly desperate because I'm graduating at the end of 2026 and I don't want to remember this as my life in high school, I want to rise up to the top, very very badly.
