Joy and Jerri say their 24-year-old daughter, Jessi, has a severe addiction to alcohol and suffers from bulimia, and her self-destructive choices are destroying their family. Joy says Jessi lies, manipulates and steals to get alcohol, and was recently arrested for assaulting her father in a drunken rage. Jessi’s father, Jerry, says they’ve spent thousands of dollars trying to help her but nothing has worked. Jessi admits she drinks a gallon of vodka a day to function and says she keeps a lot of secrets about her behavior from her family. Is she ready to come clean -- and get clean for good? Plus, Jessi opens up about a painful childhood experience -- could this explain her behavior? When Dr. Phil throws her a lifeline, will she grab ahold?
