I don't cut. I don't post here because I don't know what advice to give, or how to be supportive, but I often read the posts. I would never say anything bad, I know that none of you would CHOOSE to want to do this. That's like saying that someone who is depressed should "snap out of it already". (I hate that remark)
I did go a little crazy on my leg once, so I have a little baby inkling as to where you are coming from, even though it was only once. If ever I think that there is something I can say/reply to without sounding like a total outsider to be supportive, I will.
