Why are your poems so dark Jude?

Why are your Poems So Dark Jude?

It’s not just my poems dear reader.
Everything has darkness.
The moon has a dark side. 
That is hidden from view.
When the maker cried
Let there be light.
He left the darkness of night.
Even the purity of the poets 
crisp white  page
Is nothing
without the spilt black letters
of his heart. 
I think you may have wished
to ask of me
Are you so sad Jude.
I answer quietly.
I am like the moon
My darkness is not in view.
