Heartache fucking misery

What was my mistake,
Darling, just tell me what the fuck I did.
My sanity is draining and taking me with it,
I'm sick of sadness.

The dark no longer holds me,
It beckons me towards the razor.
I taunt myself from the hatred,
The confusion and loss.

All I want is a small reason,
Superficial explanation.
But nothing...
I fear the blood will soon start running..
