Is overcoming fear, anxiety and despair overcoming doubt?

This morning in the chapel some of the young interns led worship. We listened to the reading from John's gospel about the risen Christ appearing to the disciples on the other side of the doors locked because of their fear.
Meanwhile at the front of the chapel each held a large piece of paper with a word on it - despair, depression, fear ... As the reading progressed one person gradually moved among all of the others tearing up the fears, feeding each bread and giving them bread to share with others. It was a powerful and simple message, overcome fear to overcome doubt.
Meanwhile Maggi Dawn has been writing passionately about doubt here.
