I'll eat myself

I've always felt different I'm happy, full and normal The day ends and the feeling returns a pressuring dark hole opens up my chest threatening to swallow me whole It's mouth is on me. its teeth cornering me, all around me and, in it's tongue my body lingers backwards, Into its throat my meat and bones stumble almost falling down ready to be chewed, swallowed and turned into mush but then morning comes. And it's day. and I leave its mouth, knowing I'll return later when the night turns too reflective.
