Today is National Self-Injury Awareness Day and I'm letting somebody else explain what it's all about:
I have been aware of "cutters" for quite a while, I even know/knew somebody who did it, but I never paid terribly much attention to it until I learned that self-injury can be a warning sign for suicide. But self-injury rarely is the same as a suicide attempt.
The site I linked to gives information on why, how and what to do about it.
