A murderer inside

I am a murderer inside...
Just have to wait
My head rush has gone,
Just have to wait
To lay may pain outside.
I'm a killer when I get all
alone
Would you forgive me ?...

I am alive and I am
cruel.
I sometimes die when I
strangle my all
But nothing can get out
of all my sides
I'm a murderer inside.

Please forgive me
I want to hurt nobody
Please forgive me
The only one I kill...
Is me.
