D, Some are more adament then others. It depends upon the individual, childhood and crisis. You have one that is a little bit more stubborn and needs to keep reminding herself and others that she's not coming back. It's their mantra.
It is discouraging, but you need to let her comments roll off your back like water does a duck's back! Continue doing what you are and let her comments roll!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
