being the "weird kid" in portugal

I hate my school, one of my "best friends" literally made an edited photo of me and a random guy and she knows I hate photos. When the director found out what happened she lied saying it was just a joke between me and her, BUT SHE SENT THE PICTURE IN A GROUP, she apologized and if I didn't know that after she had spoken to the director she told everyone that I was a strange bitch I would forgive her (thanks Matilde)

she always said that I was an NPC and that I was cringe, idk if you know what a beta is but it's like those insurmountable preppies, so she was always a beta and a pick me, but she was always nice to me only since I started seventh grade, she's just spreading lies about me and now I'm called a bald lover by most of the school

what should I do?
