I'm terribly sad to hear of your loss. You're right, we're family. What happens to one, happens to all, we're connected.
My father passed when he was only 53, same age as I am now. That was 25 yrs ago, but I still feel it like it was yesterday.
Like you, my Dad taught me an awful lot of what I know, so I never think of him as gone. He's watching over us, smiling proudly.
Be strong, friend.
