Yeah, it can. Anything really can be considered addicting. If your addicted to cutting, if you feel the need to do it or depend on it it's an addiction.
It's great that you want to stop, congratulations!
Im going through the same thing. I have to throw out my tools soon too. Part with the lighter, just throw it out somewhere you know you can't go back to get it. It's alot harder than it sounds, I know, but you have to do it. I believe in you
When your thinking of hurting yourself how about trying the alternatives?
Wishing you luck
