Mary Kennedy’s friends held a memorial service in her honor earlier this week. One friend remarked to a New York Times reporter that during the eulogies “there was nothing about depression.” She felt that people had gotten the wrong impression of her lost friend. “No one remembers her as depressed.”Mary Kennedy committed suicide, hanging herself, at the age of 52. She had struggled with profound depression for several years.And there, in the friend’s misguided remarks, is a terrible problem. It is still with us: the stigma of depression.
