I'm sorry for your loss Jenny. My condolences to you and your family. It's so awful to see someone decline like that, but even knowing that it was their time to go, it's still hard to accept. We're never really ready to say goodbye to those we love.
I am so very sorry for your loss! Please tell your Mother how sorry I am for her loss and how envious I am for the incredible marriage she had. What a wonderful couple!
