First off, this is NOT about suicide. It's about cutting, which is not the same thing. This is something (when I was young and unable to control or understand my emotions) i did and even a dear friend of mine did (though I flipped out so royally he didnt do it again). I do not condone it, I am merely trying to...explain it. Well, the emotion behind it. It is as bad a habit (yes habit) as the other things mentioned in this poem.
