Sincere condolences Kerry, I lost my dad when I was 18 and he was 66 also. Don't let guilt bring you down. Try to focus on positive things and time shared. Yes you will be sad for a long time.i think of my dad everyday and its been 30 years ago. I think of some of the funny things and tell my wife stories about him and it helps. Think of the years you had him and plan on seeing him again...
