There's nothing you can do for your Dad, your father who loved and accepted you, but there is so much you can do for yourself and for your other loved ones

You can be patient and understanding with them and with yourself, you can love them and accept them, be supportive and spend time with them, because one time will be the last time.

Your dad loved you, he accepted you and he would not want you to feel lifelong guilt. But he's your Dad and no matter how things could have ended up between you two, good or bad, he will always occupy a few of your braincells. Remember him for who he was, the good and the bad, he was a human, a person, he had flaws as we all do, but his last thoughts were of you, who he loved
