Marc, 22, unearths the abusive childhood memories that gave rise to his bulimia and OCD, including feeling neglected by his drug-addicted mother who also suffered from an eating disorder that ultimately led to her death. He feels disconnected from his father and fears he will follow in his mom's footsteps unless he can get a handle on his disease. Meanwhile, 38-year-old Kristy is a former model and mother of two who battles bulimia, and binges and purges several times a day to keep her weight down. She blames her mother's criticism for her body image issues and wants to regain control of her life before her disorder destroys her family.
