Unhappiness is a Rat King that grows, tangles, and gnaws from the inside. It helps however to be distracted now and then, to smile and pretend you’re happy and content. A person can live like it’s not even there. You start getting used to it. It hollows you out as it eats your insides. But it also fills you up with its hairy warmth, despite its teeth and claws. The multiple hearts beating, the friction of fur on fur, the heat from the collecting feces, can be strange comfort sometimes. Like a hug coming from the inside. Life can be manageable with a Rat King.
Unfortunately, it would eventually grow too big and burst forth, grossing everyone out.
As it scurries off, and struggles to run away from the light, it’s a little difficult trying to be happy. Not only are you a hollow shell of your former self, but you’re also a disgusting, bloody corpse on the floor.
