like what you did.
i had some anger issues with dad...11 years before he died...he had a massive stroke and I had a baby who was born and died at 2 months.
did grief therapy around son's death and worked heartily on forgiveness as well as healing from the intensity of a child death...that's where the therapist started me...when i became aware dad was dying (about two years before)--had a resurgence--felt like rage...and so did exercise to make myself feel better.
it was good to know that had forgiven him when he died...but kind of by accident.
