Thank you Montrovant. My motivation was one of concern. Where I come from those I know who self harm would DIE if it got out in public.
My cutting, while similar in a lot of ways to others (at least, from all I've heard on the subject), was also quite different in that I was very open and public about it. I kept most of it to places that could be covered up (the vast majority of basic cuts are on my upper arms), but I also carved words in both of my lower arms. I had friends do things in my back shoulders and, on one or two occasions, my stomach. I did it at school during lunch or while just skipping classes, while hanging out with my 'clique'. I remember, at least once, simply breaking a glass bottle someone had left and using a shard of glass to cut something. I also used the blood to draw things on my walls sometimes.
The really odd thing about it all isn't so much my doing crazy carving, but that there has never been any particular cause for it. No tragedy in my life, no abuse, other than a stretch of a couple of years in my pre-teen time, I've lived a middle-class life of relative comfort. Apparently there's just a bit of crazy in my family.
I had mostly stopped carving before I became a nanny and stopped completely once I did. Actually, I think the last time I had any carving done was when shortly before I became a nanny, and the couple who 'hired' me were the ones doing it.

I've still got a video of that on youtube.
It's hard enough to try and explain to the little one why I have the word HATE carved in my arm, I couldn't have her see it freshly done! She doesn't need any of that crazy in her life.
