Skin can cut, veins can bleed, but physical wounds, can heel and won't be seen. Other are invisible, but they cut, deeper than anything that bleeds.
Nothing will make it heal, it will never get off your mind, no weapon was used, just the breakdown of your mind, and the destruction of self.
Desperate for lifes end, your shadow begins to leave, mind is racing, delusions take their place. Delirium consumes you, you know of only one way out, wrist deep in your own blood.
After death, the pain grows stronger, it will never go.
