I think you are working in the right area.... but you must "know" in your head what is wrong with SI... it isn't healthy... it's acting out... it's a cry for help... it's a way to take control... it's a way to feel alive.... or all or these or others.

But IMHO that isn't where you should put your efforts in therapy. I think working on why you feel that you need to do this. The cause is what's driving the actions. If you took away these actions without easing the cause, they you would only find other actions to take over.

In one sense, it's a pretty black and white scenario... when viewing the basic problem. Of course, each person adds nooks and cubbie holes and issues that complicate it. But you can work this out. It can become less controlling of you, and you more controlling of it... It can because only a thought from time to time... and it can become something you USED to do...

It's a good path you have begun... not easy... but a good one.
