Just regress and beat them the same way they beated you. They won't ever mess with you ever again.
Here is how I would deal with my bullies:
Bully #1 Aisha: "you are a kid, enough with the roleplaying as Joonghyuk."
As we can see here audience, Aisha is an ableist bully who is clearly anti-autistic for accusing the author of being a kid and taking advantage of the author's easily vulnerability. As a result Aisha could of led the author to commit s^,|*_•e as many people in real life have actually died due to massive bullying.
Never let the bullies get to you, you are always loved even if you hate yourself because you are at the very least loved by someone.
