Well... once people who I loved found out it just hurt me more to see them so worried about me. So that was one reason. Another was being scared of other people finding out. I also had a good dose of cognitive dissonance going on, and so in order for me to believe i could get better one day, i needed to stop behaving in these ways.

that doesn't mean i don't think about it a lot though. I think it's hard to find one specific reason to stop doing it... and in the end, it has to come from within yourself. you have to WANT to stop. Intrinsic motivation all the way...
