Renae says her 14-year-old daughter, Amanda, was a model child and a parent's dream but in the last couple of years has become a rebellious and violent teen. Renae says Amanda's anger is oftentimes directed at her. She says the teen has punched her -- as many as 50 times in the last year -- has knocked her teeth out, called her names and has kicked, bitten and spit on her. Amanda admits that she doesn't respect her mother -- or any authority -- and that she has a violent temper, but says, "Fights find me.” Then, Amanda’s stepdad, Mike, weighs in. Hear why he calls his stepdaughter Satan and how he feels about her outrageous behavior. Can Dr. Phil help show Amanda more effective ways to channel her aggression -- and her family better ways to cope with her? Then, Courtney, a police officer who works with juveniles, says that despite her training, she can’t control her defiant, eye-rolling 16-year-old daughter, Sabby’s, bad attitude. She says when Sabby doesn't get her way, she works herself up into a rage and has pushed her grandmother, threatened to kill her younger sister, and was sent to and kicked out of boot camp just recently. Then, meet Sabby, who maintains her defiance with Dr. Phil. Can he get through to this tough teen? If you are having a difficult time raising your teen, don’t miss this all-new Dr. Phil.
