During the teen years, a person is dealing with understanding their own identity, where and how to fit in with peers, rapid physical changes, and challenges in making healthy, sound choices. When these factors collide, many teens need additional support to cope.
Major loss and life changes (such as natural disasters, divorce, remarriage of parents, relocation, death in the family, etc.) can bring about a host of emotional responses resulting in isolation, arguing, defiance, and other unhealthy behaviors. It is usually during this time that the teenager’s family and friends notice significant changes in how they present and behave.
