I don't know you or your wife. I am very sorry for your loss and send my condolences. I wish I could ease your pain.
There are too many moments like this that people experience in our travels through life. I don't know why I am prompted to do this, since I am not close to you or your family, but I want to post something my father wrote. He died of cancer at 55 and left a big gap in my mother's life due to his age at the time. While a massive impact for my siblings and I, we were in our 20's and "living our life". These things impact life partners differently. My father passed near Thanksgiving so he wrote this at that time of year.
A Blessing
There is the season for Thanksgiving
There is the season for all things
A season to be young, playful and innocent
A season to be old, patient and wise
There is a season for learning
And a season for earning a living
A season for adolescence, uncomfortable and confused
A season for surety, adulthood with its commitments
There is a season for health
And a season for illness
A season for revelry, games and celebrations
A season for philosophical, spiritual introspection
There is a season for service, devotion to others
And a season to sit on the throne of our making
And so on
