"These children are at high risk of becoming emotionally unstable and of becoming drug, alcohol, or sex abusers. Children at different ages display behavioral changes that might indicate that they are at risk. Those between the ages of 2 and 8 might exhibit the following signs of stress: regression (displaying infantile behaviors, thumb-sucking, bed-wetting), depression, crying, anxiety, clinging, and temper tantrums. Indications that teens are troubled include poor grades, change of friends, isolation, distancing from family, oversleeping, drug or alcohol abuse, eating disorders, cutting, lying, and keeping secrets."
