Hugs. I’m sorry for your loss.
We’re all puzzle pieces, each with our own purpose in life. We have varying amounts of time to finish our work and to be the people in that particular place, in that particular time, that God wants us to be. And sometimes it isn’t so much about a particular accomplishment, as it is about the little things that we do while on that path.
It’s incredibly difficult dealing with people who were taken too soon-- who still have so many things they could accomplish. Young moms taken from their young children are hard. Young fathers taken from their young children are hard. Young children are super-hard.
I’m happy that your mom had the chance to accomplish as much good as she did in the time she had. Pray for the repose of her soul, and pray for your family tree. Do what you need to do to carry on what you would have expected her to have done, for love of her and love of her memory, and do your own individual work as well.
Big hugs.
