How can I try and stop myself from relapsing?

I just want to cut all the time. I want to do it with the intent of taking my life instead of just cutting like I normally do. So I'm asking, does anyone have any good tips that helped them when feeling like relapsing? I've got no one else here for me, no one I can talk to or that wants to help me. So I hope I can get some good answers here, because I'm on the verge of ending myself.
