I would recommend, when the client is ready, that deep anger from others’ injustices can cause anxiety and depression in some cases. Then I would present the Forgiveness Landscape questionnaire from my book, The Forgiving Life, as an exercise for the client. This questionnaire leads a person to reflect on all who have very deeply hurt him or her from childhood to the present. The client then ranks the people from the deepest hurting to the least (but still in the context of being treated very unfairly). Those at the top of the hurt-list are the ones who could be contributing to the anxiety and depression because of their past unfair actions against your client.
