They may feel tired, dragged out, or conversely, have excessive nervous energy. They may feel guilty or worthless. An adolescent with a depressive illness, if not given the help they need, may turn to suicide. Normally, saddened adolescents complain or talk about their sadness while they try and do something about it. Teens, in general, will push away their parents and rely more on relationships with peers.
Teenagers can become unhappy for many reasons.
Teenagers who become very stressed will sometimes become depressed often, this will happen in a family in which other family members, regular or grandparents, are or have been depressed. Use positive discipline. Shame and punishment instead of positive reinforcement may leave feelings of worthlessness and inadequacy in children's lives. Avoid overprotecting and overdirecting. Protecting children from too many things, not letting them make a mistake, and directing everything they should and shouldn't be doing comes across to children as their parent's lack of faith in their ability to do anything for themselves.
