A very informative research article concludes with this phrase: "Support groups help survivors advance with their healing after a suicide loss" (See link). However, what is described as "healing" sounds more like a simple easing or relief from the emotion maelstrom that follows a suicide. The suicide postvention literature plays just as fast and loose with terminology as the suicide prevention side. Healing has a very specific meaning and connotes an outcome that may not be achieved after experiencing a severe traumatic loss such as a suicide. Healing implies restoration of wholeness even when used figuratively. In general, studies of suicide loss survivors report that most recover and arrive at a "new normal." However, like all trauma victims they are changed in many ways by their experience. They may come to function better but they are different from who they were and have recovered rather than healed. Some qualities come back; others emerge. The bilateral amputation that is a suicide does not heal over like the cut finger. Misconceptions in the professional literature tend to find their way into lay commentaries. Those struggling with an emotionally devastating suicide loss may take "healing" at face value and pursue it instead of simply coming to terms with their loss and working towards who they now can optimally be not chasing who they were. That said, has anyone operationally defined healing from a suicide?
