[Broken Constellation]

I hate to say it, but it seems like you have an addiction. On the bright side, though, it'll most likely be much easier for you to stop, since you've started recently. I've been cutting for years, some months I do it more than other months, and some, I don't cut at all. One thing that has been helping me to not cut when I feel the urge, is, instead of cutting, I snap a hairband [or rubberband] on my wrist. It gives you a painful [slap] sensation [if that's what feels good to you] and whenever I think about cutting, I snap it against myself, and it's sort of saying "No! Don't think of/do that!!" Another good thing, is that it doesn't leave a scar or bleed.
Some day, though, you should be able to not have to use the band to fight off the urge.
Good luck, I hope this technique helps.
