Sorry to hear that, Fix. I know how it feels. My father passed away a year and a half ago, brain tumor at 56. My father in law died of cancer at 46, 2 weeks before the wife and I were married. I miss them both.
I won't tell you it gets easier, you know as well as I do that that is a crock. It does get easier to remember the good times, though.
I hope he went easily and peacefully, and wish you and your family the best.
