Why did I do it?

Why did I do it?
I held the blade, inched it forward just a bit,
I let the razor pierce,
In amongst my classmate's jeers,

Oh, God why did I do it?
Crimson seeped forward as the pain bit,
Black blood swarmed the blue walls,
As I was engulfed by death's cold jaws,

Why did I do it?
All I was craving,
Was one last hit...
