Haha I am nuts!

Stuck,
In two different worlds.
Escape; impossible.
Darkness all around.
I am going insane,
Traped in my mind.
I walk,
The dead follow.
I my room,
Tiny not big,
Black not light,
Dark not plain.
I go to my rusty draws,
Get a knife.
I look at the knife for hours,
Just laying on the bathroom floor.
I wonder would happen?
If I was no more.
I raise the knife to my wrist,
I cut the vain.
Blood burses out,
I hold my breath,
For a scream will trigger emotion.
I quikly sit up,
Let all the blood flow into a big cup.
It hurts so much,
But I don't make a sound.
I sit there,
Hours on end.
There is little blood that flows through these vains.
I start to laugh.
I grab the cup,
Drink it,
I have a breakdown,
Realise I am insane!
I pass out...
I die...
In my head..
It was all a lie.
I wake up,
In a metal hospital,
What's going on?
The stick a needle in my arm,
I don't go to sleep.
They stick another,
It still doesn't work.
See, for I do not have any blood,
So you can not put me to sleep.
An evil laugh I produce.
They stare,
You really are carzy,
They say.
