Ciao,
Trust me when I say that I know the feeling. I'm on the verge of relapsing myself, and I think that you are very strong for reaching out, even if it's just on this websight. I agree with Dez, she has some really good advice.
My advice would be to identify what need you're trying to satisfy when you cut, and looking for something else that can satisfy that need as well and trying it. I don't believe that there's one magic alternative, but a multitude of them that will work for us at different times.
I'm very sorry to hear about your past situation with your boyfriend and parents and I strongly advise you to talk about it with others if at all possible. I know that sometimes with abuse you literally cannot speak about it, even if you want to. I've been there before, but talking really does help. Is there anyone that you trust that you can talk to? Also, it could be really good for you to get out of your house as much as possible.
I hope that this helped and I wish you the best of luck on your journey. <3
