Although Amy's addiction is different than Jennifer and Tracy's, Dr. Robin says all three women have something in common—they are searching for validation.
Dr. Robin says that Amy is allowing herself to be defined by relationships with men, instead of looking within to find self-worth.
"The issue is about building a self," she says. "'How do I build a self that is not dependent on anyone else?' It is the task of every human being, but particularly of every woman. ... I don't know of another task that is bigger for any of us than to say, 'I am worthy simply because I am.'"
