My grandmother from time to time starts talking about when she will die. She gets depressed and starts looking forward to that day. She'll be 86 in a couple of weeks, but is in great health for her age. She lives with her daughter, but that started as much because my aunt used to be on travel a lot and didn't want to leave her house vacant so much.
One of the worst times was about the time my oldest child was born, 9-1/2 years ago. He was fussy and didn't want this person he'd just met to hold him. Grandma started to cry. She was convinced no one loved her and there was nothing to live for and she may as well just curl up and die. I was shocked, what do you say to that...anyone who has ever held a newborn baby knows that they cry for lots of reasons that have nothing to do with you.
Fortunately, there were other young children in our family at that time. I reminded her of her 4-yo granddaughter and her 3-yo great-granddaughter who adored her. Given her family history, it wouldn't be unreasonable for Grandma to live another 20 years...long enough to enjoy the girls' weddings.
Her eyes lit up, "Their weddings? You really think so?"
Well, the girls are teenagers now...Grandma's about halfway there. Every now and then she thinks about giving up, but I know she looks over at those girls and their younger siblings and cousins and sees how much they've grown and how much she would've missed and how much she could still miss.
