Adolescent depression is a complicated situation. Most teens feel "down" at different times. Afterall, adolescence is the period of physical, emotional, psychological and social changes. Teens can feel overwhelmed, confused and moody. It is therefore rather difficult to recognize true depression vs. typical adolescent behaviors. Here are some possible markers:
A change in friendships
A change in school performance
A change in eating or sleeping habits
Extremes of emotions, including anger and rage
Overreactions to criticism
Lack of enthusiasm, energy or motivation for previously enjoyed activities
A sense of sadness and/or satisfaction in life
Substance abuse
Sexual promiscuity
Statements about wishing to die or giving away personal things.
If you feel your teenager is experiencing depression, it is important to receive prompt treatment. Depression has been linked to poor school performance, school truancy, substance abuse, running away, feelings of helplessness, eating disorders, sexual promiscuity and suicide.

Contact your family doctor, school psychologist or other counselor, who can refer you to a qualified professional.

Parents can really help:
Watch your child.
Keep the lines of communication open by expressing love, concern and support.
Make sure your teenager has someone to confide in ( and sorry to say, it sometimes has to be someone other than you).
Don't minimize what your child is going through. It may not seem serious to you, but it does to him or her.
Keep the appointments with a mental health professional and go with your teenager.
