Oh no... that's so sad. I'm sorry, I can imagine how hurtful that would be, and the double whammy of worry that she may be having some problems with cognition and that you could experience something similar.

Family stuff is so hard. Even when they're extended family, far away.

I'm really glad you had the chance to talk to her when you did, and that you have some positive memories of her now. Fingers crossed that you can reach her son and find out what's going on!
