@MMissile My heartfelt condolences, I can relate.
We are all born to die, but that alone does not lessen the sting when those we love exit our lives.
I for one am glad to hear your father lived a long life.
My father whom I miss every single day was taken from me too soon at only 61 years young.
He never got to see my daughter or his grandchildren save one.
Everyday I see traces of his likeness, spirt, habits and traits, in the legacy he left behind in those faces.
For my part I do the best I can to honor and remember him everyday.
The only real deaths are reserved for those who go unremembered and unloved.
From the tone of your post I don't believe that will be the case for him and I believe he lives on in you.
I wish you inner peace during this most difficult time.
If you father was anything like mine he would not want you to suffer and grieve but rather embrace and take forward the best parts of him as you thrive.
