Being alone with fear can rapidly turn into panic. Being alone with frustration can rapidly turn into anger. Being alone with disappointment can rapid turn into discouragement and, even worse, despair.
The five stages - denial, anger, bargaining, depression, and acceptance - are a part of the framework that makes up our learning to live with the one we lost. They are tools to help us frame and identify what we may be feeling. But they are not stops on some linear timeline in grief.
Censorship is the tool of those who have the need to hide actualities from themselves and from others. Their fear is only their inability to face what is real, and I can't vent any anger against them; I only feel this appalling sadness. Somewhere in their upbringing, they were shielded against the total facts of our existence.
