Characteristic symptoms of critical-incident stress may appear immediately or in the weeks after the incident. One of the earliest symptoms may be numbing and withdrawal, including detachment from friends and family. Other reactions include reliving the incident, with distortions or in slow motion. Depression, sleep difficulties or substance abuse, including overeating, are other indications of trauma. Guilt about the incident or about a lack of feeling about the incident may be compounded by other factors such as prosecution by the victim's family or adverse public opinion. Difficulty getting along with family, friends, or professional colleagues is another clue. An officer with symptoms of critical-incident stress should have professional counseling or join a peer support group.
