I so know what you are talking about. Nearly 3 months ago, Hekitty had a bout with pancreatitis. I still get edgy if she look cross-eyes. Paranoia abounds when our furbabies are sick. Yesterday she yakked a hairball...just a plain old hairball (from all the overgrooming due to the now-dead fleas...and I spent 15 minutes examining the nasty wretched thing for signs of excess bile. Someday, I'll relax again. Like, maybe, a year or three.
And now, hoping I don't wake up to hearing her puke like I did this morning. I swear, that wakes me up faster than anything right now. And these last few days have brought back some horrible memories of the beginning an almost 3-week period of time that was just awful. The paranoia is still there I'm afraid.
