I was looking through my feed and came across a post from

Its a great photograph and the lines underneath struck me as something that would make a good start of a poem. So I wrote one. :)
It's hard to breathe, it's taking over
The darkness, it's consuming me
I feel it growing, while I'm choking
Feel it's need to be set free
Like a fire in my bloodstream
Fuelled by hate from parts unknown
Burns away the pieces that are me
Rages through my flesh and bone
Soon I'll be gone away forever
Something dark will take my place
Seething mass of hate embodied
Set behind my smiling face
