bluemountains, my father was a loving, concerned parent; my mother was an emotionally abusive, narcissistic alcoholic and manipulator. When my mother died in 1990, I did not feel loss or sorrow. However, when my father died in 2001, I grieved for many months. In fact, I still tear up from time to time.
To this day, these emotional reactions seem entirely normal and appropriate to me. For this reason, I find your reactions entirely normal and appropriate as well.
