Behavioral Issues cover a broad spectrum. Many behavioral issues present as mild and infrequent. Others issues seem to crop up out of nowhere. Behavioral issues cover the age spectrum completely, and can include anger and aggression, disrespecting adults, oppositional defiance, avoidance, acting out, manipulation, and codependence. If undesirable behavioral patterns are allowed to persist, they can grow into something larger and linger for a lifetime. The behavioral patterns you develop through your childhood and adolescence will be what you take with you into your marriage and future career. As adults we will be defined by our actions and our words. It is thus essential to develop self-control and healthy coping skills to handle all that life throws at you.
