I have to get it out of my chest

It is stuck
In my throat
It swells
Like a sponge
It buries itself in the crevice of my bosom
Languishing as a sea captain drowning in his ship

It is stuck
In my throat
Choking my words
Like a tarantula that crawls down in my sleep
Waking my mind to asphyxiation

It is stuck
In my throat
That which I cannot name
Encasing itself behind my ribs in its own coffin
