The fact is that many of us deal with an angry teenager, and the things that are said and done during the angry exchanges both sadden and shame us. And although it can seem like a sudden phenomenon, anger usually builds, and only the actual revealing of it is sudden. There are many causes for anger in the life of a teenager. They are dealing with an incredible change in their physical being. Their bodies are changing, demanding more of them, bursting with energy one moment and dead tired the next.
Hormones run amok, causing alarm and anxiety.
These changes often create fear in adolescents, and fear is a common root of anger. Changes in home life can be a cause of anger, if the family is dealing with stressful situations such as severe marital problems, sickness or financial pressures teenagers incapable of coping in healthy ways let you know their distress through their angry outbursts. A key cause of anger is the changing roles in the family during adolescence. Teens are moving from dependence to independence, from needing us for everything, to living on their own. That journey doesn't occur in a straight, unbroken line.
