Why did I ever trusted him and thought he was the only true friend?

[Maddison]

Its just I had this friend named Zac and we were friends for a month. He was nice to me and all that. When I went to school, his friend told me that Zac was going to rape me. Zac started chasing me. I went to his other friend to ask how I should make him stop. She told me to go up to him and tell him that I want him to stop. When I did that, Zac said "Oh but Maddi I want to have sex with you". It happened for two weeks. I went to a school councilor and she said that she'll tell him to stop. Zac denied it saying that he didn't do it. After that, Zac blocked me on FaceBook. I sorta regret telling on him. Now he has changed. He isn't the person I know now. Now the school moved Zac into the same English class as me. It made me really annoyed but after that, I started missing being friends with him so when Zac unblocked me off Facebook, he said that he didn't hate me but he didnt want me in the group anymore. Now he messages that he hated me. Now since he said it, my mum told the school that she wasnt happy with Zac in the same class so now they moved me to a different class. I am tired of Zac ruining my life. I feel like bullying him and telling him that he should get ran over. It's annoying me. I really want to kill him. Why did he be such a fake friend? Why did he told me he hated me? How can I give him revenge? Why he has changed? Why the fuck did he use me? I want to kill that barstad. When we were friends, I never was mean or did anything to hurt Zac but he did something to hurt me. I HATE HIM. I used to be suicidal over it. I almost commit suicide with a dressing gown cord. How can I give Zac the best revenge that will make him depressed like I am now? I want him to be depressed like he made me depressed. Help???
