I can only tell you how I cope with the loss of my dad; he spent his life giving me the skills, attitudes and tools to survive. I am grateful, so grateful, for all that he shared. He really cared, really loved me enough to give me the things that really mattered.
I will use them, grow them, and pass them on to my daughter and her children.
Your dad gave you a great gift; himself.
It was to prepare you for this and for all else that is coming.
You are better prepared than most, thanks to him.
God bless you and your family.
