You can do this. Is there something else you can do to distract yourself-something else must have worked since you're doing so well.
I know it's not the same thing but I quit smoking and every once so often, when things are going really crappy and I'm getting totally stressed out-I want a cigarette soooo bad. I find other things to distract myself so I don't mess up all of the hard work I've put into not smoking.
Please, try art, try writing, try ANYTHING but don't cut again. Please!! See your father there with you and draw strength from him. Ask him for help.
I'm so sorry you lost your Dad. It sounds like you love him so dearly. (((((((((((((Justice&Dad))))))))))))))))))
