Richard ~ I'm so sorry. The last thing your Mom needs right now is to see how fractured the family has become. I know you've tried to protect your Mom as much as possible. I could just kick your sister for going to her and bothering her with this right now.

Is there an elder care/advocacy program that could advise you? I know nothing about this kind of thing, but I was wondering if an unpartial, thirdy party would be best to handle this for you. I'm sure it would cost something, but you could turn over all that crap to them. Let them field the nasty phone calls, etc. While you spend quality time with your Mom.
