So scared!

I don’t know what to do anymore, I seriously need help. I can’t stop cutting, it’s all I ever think about even when I think of everything else it always comes back to my razor.
Things are so shit right now, the men who tried to groom me for so long are finally free and out of prison. One lives in my road, I’m so scared I don’t know what to do. I know they’re gonna come back for me. They promised this before they went inside. What do I do? :'(
So much shit is happening right now, I know others have it so much worse but right now I’m being selfish and only thinking of myself.
The boy I truly love isn’t really talking to me, he’s so blunt & he makes me so upset, he used to say he loved me back and that he cared for me but now he’s only making things worse. I don’t want to let go, I’m not even with him. I so wish I was, he’s been nothing but bad for me but I really can’t let go of him.
I don’t know what to do, I’m so confused and hurt and angry and upset.
I hate cutting myself, but it’s the only way I feel I can deal with things. I’ll hurt myself so they can’t! They’re gonna try and ruin my life again and I can’t deal with that again, I was only 8 for fuck’s sake :'( Why do they have to come back? Justice has not been served. Once again the courts have fucked me over!
It’s my sisters anniversary next week, I don’t even want to go to the cemetry. I miss her so much, I’ve never even met her :'(
Please help me.
