The deadly shooting that claimed the lives of 20 children and 7 adults in Connecticut focuses attention on mental health, particularly for youths and young adults.

On Eyewitness News at Six Monday, Shannon Terrell Harvey, CEO of River Edge Behavioral Health and also a licensed clinical social worker herself, says warning signs that your child may be struggling emotionally include:

- Drastic change in behavior

- Behavior that is socially abnormal or destructive

- Changes in appetite or sleep pattern

Harvey says the key is to seek an official assessment for your child quickly if you feel he or she may have a problem. School guidance counselors, resource officers, or the health department may be able to connect you, as well as a licensed psychologist or therapist.
