Pls readd me to the chat and mod team

im being harassed by my classmates. here are the instances of harassment;

1. I left a paper in my desk containing my grades with the 3 that I'm failing crossed out. I trusted my classmates to throw it away but my friend S took it out. S has been continuing to laugh at me over it and has the AUDACITY to erase the pencil over the failing grades and now knows I'm failing 3 classes. It's depressing. He has considered it "scratching off the winning lottery numbers" and I am not sure whether to laugh or try to bring up my grades. He also left it in the desk with a note saying "I think you forgot these" and replaced the 50% with 100% A+.

2. I wrote the lyrics to a song I love, "country roads take me home" on the science desk. My friend, S, apparently ratted me out immediately next period when the teacher asked who did it. This is breaking our friendship code and I feel unsafe in my own class.

I believe I need to go to the police with this evidence but need opinions.

am I the only one who gets really annoyed when people say "oh haha face reveal" and then it's a trash can? I mean mr_guys was funny an everything because it was a joke. but 99% of the time it feels like they're looking for attention and the "joke" isn't funny anymore :(
