Just a couple of minutes ago I confessed to my mom that I SI sometimes. It turns out she'd suspected for a rather long while already, and we had a pretty good conversation about it.
SIing is something I try every once in a while because I know it makes other people feel better and I want to have that bit of "feeling better" too, but it never works. I told my mom this and we agreed that, as it doesn't actually help me, I wouldn't do it again. (I'd already promised that to my T a few weeks ago also)

P.S. for those of you who recognize me from the Survivors forum, my parents weren't my abusers. :-)
