I am sorry for the loss of your dad.
I know we all would like the answers to your questions.
Fact is we do not know for sure. We can only guess.
I believe whatever your dad was mad at God about. Was
cleared up when he, crossed over. :)
And, I believe your dad will be watching over you, as he can.
Perhaps you can talk to a counselor about missing your dad.
Better way to go than in this, thread xoxo
