I got cyberbullied about three-four months ago but I can't get over it?

[hi]

It's a pretty long story, I am sorry if it gets complicated. A girl hacked into my account and posted two pictures of fat women in a bikini and sent a message to my friend's mother (my friend is a guy) saying that us two were sexy together. His mother realised that I was hacked. It took me about a hour to figure out who hacked my account because there were two girls. One of them has minor-hacked my account, but it wasn't her. She just told the other girl my password. We were going to do something on a game on facebook so we swapped passwords, but she changed it. So the girl who hacked my account said my password aloud, then started saying horrible stuff I can't say on here about me and the guy.

I never told her I found out. I kept the anger inside. The girl who hacked my account always made fun of me, she thought I liked my friend (the guy) but I didn't. She wouldn't stop bullying me about it, so I got mad on fb and told her that she liked him. She got angry and called me the b word.

So she blocked me a while ago and this is why.

We had an argument telling this other boy liked another girl. I said he didn't because the girl who hacked my account always lies/makes fun of people making friends with the opposite gender like me and my friend I just explained. Then we argued and I never swore but the girl made this terrible thing that I only half-saw in my notification..
It called me a rude b-word just because of this argument. Tons of people in our grade saw, and since I got bullied since I was 4 I said a large percentage of the grade hates me, because they do.
After that I say, "Everybody hates me."
Then the girl took screenshots of them, and that was the last I saw of her main fb account because she blocked ME. The only bad thing I said was she had anger issues because it is obvious. She swore at me for one small argument. (I didn't swear)

And she sits next to me in band and excludes me too. I can't get over this problem. I have about two more accounts the girl added me on, and I am going to get revenge.
