Courage and Motivation?

I find it so hard to write,
These words don't flow anymore,
Only sometimes can I do this,
What happened to it?
The inspiration,
The motivation.

Is it this medication?
Is it this cruel expectation?
Or perhaps it's just me,
Just who I've become.

I can't find the courage to give up,
I can't find the will to keep going,
Never sure what to do,
With these words filling my head.

Does this make any sense?
Am I blind to the obviousness of failure?
Deaf to the cries of the hater?
Numb to everything?
So numb I can't see when to stop,
When to give up on this
Fruitless endeavour?

This must just be me,
This is all that I can be,
A tiny word,
A simple sentence
Away from humanity,
Away from insanity.
Or has it already struck?
