It is important for people who are affected to share what they think and feel. A critical window of opportunity exists. Debriefing and discussing the events within 72 hours of an incident can help insure that people recover and don't end up becoming permanent psychological casualties. Both children and adults need to be shown that their feelings are accepted and understood, and not just told that people understand. Feelings should not be judged or punished, but it is important that children understand the impact of negative behavior such as hurting others or neglecting responsibility.
Many people have a tendency to rise to the occasion during a crisis.
After a traumatic episode, many people who were involved will attempt to help others. They do this to feel better and to ease the suffering of people they have compassion for. This can be a tremendous help, but it can also serve to hide from personal trauma and pain. People who experience the greatest trauma, and are busy helping everyone else, may be end up becoming the greatest casualty of all. Whatever the case, it is important to reassure people that they are safe.
