Well, she works 12-hour shifts in a cancer ward, her Mom's been unwell lately, and she lives with me. Stress? What stress?

Seriously, she's regained some color and appetite. They still want to check her heart because of the severe dehydration she's had for the last week, but the word is that it was almost certainly a nasty nasty stomach bug and that she's out of the worst of it. So now my stress has lowered a bit.
