To Lindafromflorida & carol5417. Thanks so much for your responses! That's the kind of good news I need to hear. I'm so tired and scared and achy and short of breath right now it's hard to imagine I could feel like walking and shopping soon. If you pray, please keep me in your prayers. If I can get through this next week, I think I can make it. (I'll probably be saying the same thing the week after that :-)
