I want something good to die for

The sleep used to be my escape,
The one thing I used when I couldn't take it anymore.
The thing I used when my breath was short,
And when I couldn't see because of all tears.
The sleep was my paradise,
And no one could touch me in it.
I was unbreakable and unreachable in it.

I cannot hide in my bed anymore,
The nightmares are hunting me.
I cannot handle the day,
And even less I can handle the night.
I want to hide from my thoughts,
But what shall I do when the nights are even worse?
