If you cannot guess, the 'disease' = clinical depression.
The poem is about a relationship that broke down because of my selfish behaviour.
It's slightly autobiographical.
As the first line shows, I was very 'emotional' while writing this piece, so it kinda sucks lol.
'Why is it that this emotion just will not ease?
My stomach churns; I feel you treat me like a disease.
I've got this relationship on a life support machine
And without you there is no shoulder on which I can lean.'
