Hi, I am new to this post and I don't know the background to your situation with your father, but I just wanted to offer some support. My father died exactly one year ago today. We had a great relationship, I can't imagine losing him otherwise. I'm sure I would have had so many regrets. That is the one thing that I am thankful for and it gives me peace - is that he knew how much I loved him and I knew he loved me. If you feel like reaching out for your father, now is the time to do it, for the both of you. You never know the inner peace that comes with it, while they are here and after they're gone. I think the worst thing you can have in life is regret. My thoughts and prayers are with you during this very difficult time in your life.
God Bless you and your family...
