I've often roleplayed in my head how I would handle an emergency. I work on a nursing unit so chaos and tension is a matter of course.

After Katrina, even though my home had power and only a couple of bald spots where my shingles blew off, I was a lot more irritable than usual; short tempered at things over which I had no control. Trouble sleeping and trouble concentrating.

I kept appologizing to my co-workers for being an ass and they were quite forgiving though I felt I had let them down (being the charge nurse and expecting to be the "source of calm".

I guess we don't know how we're going to act in a given situation until after it's over.
