The opinion which other people have of you is their problem, not yours.
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.
What is important is to realize that whether we understand fully who we are or what will happen when we die, it's our purpose to grow as human beings, to look within ourselves, to find and build upon that source of peace and understanding and strength that is our individual self. And then to reach out to others with love and acceptance and patient guidance in the hope of what we may become together.
