How can a depressed person regain their sense of self?
Therapy can be immensely helpful here. Obviously, not everyone to whom a traumatic event happens becomes depressed. And not every person who becomes depressed has had a catastrophe befall him or her. In fact, if a person suffers a loss and then becomes depressed, it may well be that they weathered the loss in fine style and then succumbed to a much less obvious psychological or biological trigger. Therapy can help them think of the traumatic event, and how they are relating to it, from a productive point of view, rather than to dwell on the negative aspects of it. They can learn skills to empower themselves and strengthen their ego, and their ability to cope.
