Understanding of Cutting

One cut, that's all that I need,
Open my skin and watch it bleed...
Releasing the pain that's held inside,
It's all coming out slowly in stride...

Some people say I'm trying to kill myself,
But people don't understand me at all too well...
I hold everything in until I can't anymore,
Then this is what I cut for...

I vent to myself and a sharp blade,
Eventually the marks are sure to fade...
I break the skin to feel that sting of pain,
It sends a sensation straight to my brain...

This makes enough in me to feel like I'm OK,
I'm ready now to head out on my way...
The fake smile is painted once again on my face,
And I'm ready again to handle this hell of a place...

I'm doing this ONLY to myself,
And I do understand it very well...
So please tell me why it's such a problem with you?
Tell me now what I'm supposed to do...
