I think my mind is not my friend.
It troubles me incessantly
With doubts and worries to no end;
And glows rather fluorescently
When I would rather it be dark
And quiet. In the still of night
It circles ’round me, like a shark;
Each minute, taking one more bite
To wound me in my tired state
And keep me an insomniac:
Who can’t look forward, cannot rest
And cannot bring
Contentment
Back

I completely relate to this; great description of insomnia.
Oh, I don’t know this feeling…been there many times!
Well done.
