Marge, words fail me to express my sympathy for you. Seems so unfair to have this happening to such a loving sweet lady, especially so soon after you have lost your lifetime partner
But know that now John is out of his suffering for good, and probably catching up on things with your hubby in a better place now. And they will continue to watch over you lovingly.
You are loved so much by so many people. My warmest thoughts and best wishes are with you.
