endure, in enduring grow strong.
I'm sorry for your loss, and hope that you feel support from your family and close friends.
Though I have memories of my maternal grandparents, I wasn't very close to them and didn't really feel anything regarding their passings or burials, same with my father's brother who died a few years ago. My paternal grandparents passed around my own birth, so one of them I never met and the other I have no memories of. Every once in a while though, I get very worried and scared about how I will endure when either of my parents pass away, while there's hopefully still a lot of time left -they're between 55 and 60- I feel I will be very lost without having their support, even in twenty to thirty years time - I'm little over 30 now, and will be about their current age by then.
