Threats of suicide are a cry for help. Always take such statements, thoughts, behaviors, or plans very seriously. Any young person who expresses thoughts of suicide should not be left alone and should be assessed right away. Talk with your child's doctor about suicide and have a written emergency plan that you share with trusted others.
Many parents develop a written contract with their children. In it, the child agrees to alert parents if they are starting to have thoughts of self-harm. The parents agree to help the child interrupt the behavior in a nonjudgmental fashion. Examples of this could be as simple as taking them out to dinner and talking, or as intense as taking them to the emergency room for assessment and a possible inpatient stay. The important piece is the fact that your child knows you are approachable and nonjudgmental when help is critically needed.
Any child who has tried to commit suicide needs a physical checkup first to rule out life-threatening health problems. They should then get a mental health evaluation and treatment until they are stable. This often will take place at an inpatient facility to make sure of the child's safety.
