I started this year, about 3 or so months ago. I'm 12. Sometimes if I just need to feel pain to get out of the fog on numbness i only cut a little, like scratches, but if i'm really hurting, or the little voice in my head that is me won't stop whispering her horrible truths, then I cut really, really deep. One time it wouldn't stop bleeding for an hour and I almost passed out. The longest i've ever gone is a week, and that was under 'special' circumstances...
