Dan,
I have looked at this topic several times hoping that something would come to me to say. I have visited your websites to try to get a better idea of who you are, hoping that would give me some wisdom to say something meaningful. All I can say is that if I were in your place, I would be devastated at the loss. I am so sorry for your loss and pray you'll heal and pour yourself into your children and grandchildren.
I used to do all the production for a cable channel that featured health and medical reporting. I shot interviews with a lot of cancer survivors and they all said they wouldn't wish on their worst enemy, but wouldn't have missed it for anything. Those are hard emotions to understand for people who've not been touched by a life threatening illness. Over the five years that I did that, every now and then I would find my assistant quietly crying in her office. That meant another of the people we had been close to had lost their fight.
Please accept my condolences.
Warmest regards,
David
