I don't know if I would say she's mentally ill. I guess she could be, but I also think it's possible she's just an attention whore of the highest order. It would be possible for her to go on her crusade to get to 1,000 without all the fanfare -- that's obviously her choosing. Good or bad, she wants the attention.
That's why I made the Kirstie Alley reference before. You think that chick really wants to lose weight? Nah, because then she wouldn't have a TV show anymore and people would forget about her. Or how about Mackenzie Phillips milking her drug abuse for years and years after her career went down the shitter? Then when that finally got old, she comes out with the bombshell that her dad molested her. Since her acting career is done it's the only way she can stay relevant. Now this lady is going to become famous for no other reason than being a fattyboombaladdy. Sweet!
