Last leg...

If I survive, I'd be surprised. All I'm saying is I don't want to die, but I might. Better wear a pair of my good shoes to bed tonight. If I don't make it, someone's gotta wear a really big, churchlady hat to my funeral. It'll cheer me up. Thanks.

Sickly:
1. Affected with disease or ill health.
2. I think I'm dying.
