I know I already said a LOT, but I remembered one more thing that I found very useful when I quit. Think of the urge to cut like a wave that you just need to ride out. In my experience, if I could just put off or delay cutting for a while, sometimes the urge to cut went away. Imagining the urge like a wave that gets really strong for a while, but will eventually subside might help you to step back and observe the urge without having to necessarily act on it. I also have found in the past that it helped me feel safer. It was okay for me to experience the feeling of desperation and the feeling that I needed to cut (without wallowing in it), because I knew I was just riding it out and that it would subside.
