@cbhelp,
Repeat after me.
Quote:This guy is an asshole and a loser.
I am not the mean things he says I am.
My true friends (and I might not find true friends until I'm out of High School) don't believe a word this lying asshole says.
I am worth more than that.
I do not love people who treat me like dirt. They do not deserve my love.
There are more important things than this.
Continuing going to get help and tell the folks in charge that you're being bullied. Because that's what this is; it went past a simple breakup a long time ago. And, frankly, he seems to have emotionally abused you when you were dating.
I hope you can get help to stop the bullying. And I also think you should consider talking with your parents about getting some help with regards to what seem like self-esteem issues. If someone kicks us, we don't love them back. That doesn't stop the kicking or get it to be somehow, magically, 'right'. It usually just gives them permission to kick us more.
You don't deserve to be kicked like that.
As they say, it gets better. Know this.
