Nasty Bug

It isn’t fun this feeling sick. It isn’t fun at all. The bed is sorta rocking, and I feel as though I’ll fall.
A bug that’s really horrid, is a red hot firefly. Perhaps that’s why I'm burning up, he's a nasty little guy.
Or maybe it’s some other thing. Like a swollen slug type dude, that has bloated up inside my tum. and turned me off my food.
