Voices *trigger*

Why are these voices inside me head?
The voices that tell me I should be dead.
The ones that beckon me to my blade
they congratulate me on the cuts I've made.
The deeper the blade sinks into my skin
the voices get louder, knowing they'll win
They egg me on, cut more! cut more!
Watch as my blood drips down to the floor.
Red turns to black, can you hear the cheers?
cry in blood, but never cry tears.
The voices recede deep in my mind
leaving me to explain the scars left behind.
