I know you and I have never really conversed, but I am very sad over hearing that your father passed away.
Optimistically, he is now at peace, no longer feeling any pain or suffering.
While it's perfectly fine to deal with a loved one's loss, just try your best to focus on his life, rather than those last few months or so when he was ill.
My thoughts also go out to your daughter, I know this is a very hard time for her and you as well.
My condolences,
Zig
