Holly says her 24-year-old sister, Andrea, is an intimidating bully who verbally and physically attacks people -- including complete strangers -- and her behavior is ruining their relationship. Holly says she’s been feeling the wrath of her sister’s anger since they were kids -- when she would lock herself in another room to avoid Andrea’s aggression. Now, Holly says Andrea embarrasses her with her mean comments and nasty confrontations when they’re out in public, and she’s tired of walking on eggshells around her sibling. Andrea admits that she’s judgmental and angry but says she enjoys the rush of power whenever she erupts, which makes her feel “fearless,” “strong” and “unstoppable.” Dr. Phil faces off with Andrea. What’s at the root of her anger? Will she let down her guard and work toward healing the wounds of her past -- and mend her relationship with her sister? This program contain strong language.
