Denial, anger, bargaining, depression and acceptance are the five stages of grief. But life doesn’t always move in a straight line. George A. Bonanno, professor of clinical psychology and chair of the Department of Counseling and Clinical Psychology at Columbia University’s Teachers College, joins host Krys Boyd to talk about research that shows a complex pattern of grieving and new insights into resilience. His book “The Other Side of Sadness: What The New Science of Bereavement Tells Us About Life After Loss” is now out in paperback.
