I know how you feel in a way. My grandma is 82, she'll be 83 next month. Physically she's in pretty good health. However, since 1993, my grandfather, her mom and dad, 2 of her sisters and 1 brother have died. My uncle had a stroke last year. She often talks about wanting to "go home". It makes me really upset when I hear her talk like this. But, I know she's sad to have lost so many people.
It's rough no matter how you look at it
