I'm no psychiatrist, but you have to question how helpful the role of Professional Victim is to her recovery. Her whole gig since Liberty X has been "Michelle Heaton's battle with cancer gene", "Michelle Heaton's battle with menopause", "Michelle Heaton's addiction to diet pills", "Michelle Heaton's battle with alcoholism" and at this stage it's her only means to staying in the spotlight. The TV gigs and magazine articles and Lorraine series are probably the family's main income.
Yeah, she's clearly been really unfortunate with her health, and you can throw a "raising awareness" tag on it, but realistically the saga stories will continue until she finds a way to make money that doesn't include using Lorraine as a therapist to keep herself in the spotlight. And there's a real ominous feel to someone declaring sobriety and recovery and "you can do it too" a few months after she entered rehab.
