No matter what you do, once there is a loss, no matter if a position, separation with a partner or a parent, there is a normal process of grieving.
We need to plan this time and go over this process. It is also normal for people to escape this process, because it can be very difficult to accept that something we have taken for granted is now gone. It is a very uncomfortable process. But as life teaches us, there are cycles and the only thing we need to do is to ensure that we are most of the time in an uptrend cycle.
To do that, we need to bring back the lessons learned and move on.
