(Original airdate: December 5, 2011)When does sibling rivalry cross the line into abuse? Sheila, 54, says her daughters, Tamara, 37, Daria, 32, and Shirley, 29, take their fighting to the extreme. But the sisters say Sheila is a narcissist and sociopath who has pitted them against one another and failed as a mother. They say Sheila was an absentee mom who served jail time for beating one of them and turned a blind eye to the molestation of another -- and now they're resentful. See what happens when the fractured family faces one another. Can Dr. Phil help them start the healing process?
