The Darkness
The darkness envelops me
It seeps into my heart
Into my soul
With it comes pain and tears
With it pushes out happiness
I fight the darkness
I try to find solace somewhere
I let the tears flow
Even though my eyes are swollen
I fight the pain and sadness
I try to remember the happiness
I feel my grip slipping
But I am determined to hold the grip
Determined to not let go
Yet the darkness comes
The darkness advances
I push with what might I have
I struggle to not let the darkness in
Yet the darkness envelops me

I push with what might I have
I struggle to not let the darkness in
too many I’s I think.
not enough I AM’s
but still sometimes darkness, I know it too.
I know what you mean but this is the way it came out. I seldom edit – just let it flow out.
