Heather, a lifelong fan of Dr. Phil and a member of the Dr. Phil Phanatics fan group, drove 1,600 miles from Arkansas to Los Angeles to get help with her 15-year-old daughter, Marissa, whom she describes as "Jekyll and Hyde."

Heather says she is at her wits' end and does not know how to parent her daughter effectively. Dr. Phil invites one of the world's leading child behavioral experts on stage, Dr. Michele Borba, who works closely with Dr. Phil to impart potentially life-changing advice to Heather and her daughter. Watch while Dr. Phil encourages Marissa to tell her mother everything she is not picking up on when it comes to her needs. How will Heather react? Tune in to find out!
