I have to make a couple of corrections to this post from two months ago. First, C wasn’t sick for decades; it was several years, but not decades.
The second correction is a pleasant surprise: E is doing better. She’s regained some weight, she has a better attitude toward food, and she seems generally more positive. She’s still lost some memory and some mental acuity, and she still can’t walk, but I’m feeling more hopeful than I had been. Let’s hope the positive trend continues.
