One door closes, another door opens, we all have to move on - Thomas Hardy had it all wrong!
If you want another platitude, there's always somebody worse off than you: I lost my favorite Aunt & Uncle, much too young, when I was in my 40's, but, by the same token, my cousins, still in their teens had lost both parents within 9 months.
Enjoy what is and remember it fondly, but make your grief finite.
