The following conversation between my mom and I pretty much sums it all up:
MamaMess: [looking at me slumped over in the Pittsburgh Airport] Are you sleepy?
Me: Eh. "Sleepy" doesn't feel like the right word.
MamaMess: Why not?
Me: "Sleepy" sounds too innocent for how I feel.
[10 second pause]
Me: Ravaged. Ravaged may be more apropos.
