Depression in Adolescents and Children
Childhood and adolescence are normally marked by strong and often rapidly fluctuating emotions, which may have led to the long-held belief that young people were largely immune to depression.
That assumption has proven to be false. Children and teens do suffer depression, even depression serious enough to put their lives at risk. Children as young as 10 commit suicide, and suicide is the third leading cause of death among teens. 
While children may manifest the classic symptoms of depression, there are also symptoms and signs common to depression in their particular age group.
In very young children, the signs of depression include failure to thrive, disrupted attachments to family, developmental delays, social withdrawal, separation anxiety, sleeping and eating problems and dangerous behavior. 
A child between six and 12 years old may suffer from chronic fatigue, appear apathetic or unmotivated and have difficulty with schoolwork.
In teens, depression takes forms similar to those of adults. Oversleeping, social isolation, self-destructive behavior, and a sense of hopelessness are common signs. 
Children considered at high risk for major depression or dysthymia include:
While depression generally does not disappear among adults who have not received treatment, it will do so within a year in about 90 percent of children. However, it reappears within two years of the initial episode in about half of formerly depressed children, and within four years, 75 percent will suffer a recurrence. Worse still, about 35 percent of formerly depressed children will suffer major depression within one year of their first attack.
It is irresponsible to assume that a depressed child or teen will simply “get over it.”
