Barb,
I can't help thinking how much stress you're under and it's attributing to your health issues. I feel horrible and have been worried for you. It's so difficult when our parents old age health worsen and worsen and worsen. My sweet MotherInLaw was 89 when my FatherInLaw couldn't care for himself. I hope all your doctors get to the bottom of your problem. And I hope others do pitch in with your patents. You will continue to stay in my prayers. Wish I were closer!!!
Big Quilty hugs!
Sheri
