CJ, my sincerest condolences on your loss.
It's been a long time since my Dad passed on, 20 years this year. He will never leave you, trust me.
If it helps, sit down, clear your mind, and re-read his obit you posted and look at the wonderful legacy he left us - all of the children with families, 15 grandchildren and 6 great-grandchildren. What a blessing for him and his family.
Be at peace my friend.
