Brian,
In just over the last year, I've watched first my mother, and then my father dwindle, suffer and die. As sad as both of those occurences were, they weren't tragedies. They were each in their eighties and had lived long lives. That is what happens. For a young man to die like this is tragic. All the more so because he leaves behind a yound son.
You have my deepest condolences and my wife and I will continue to pray for both you and John's family.
Go do what you have to do. We've got your back.
-- John
