Something must have happened in her life around the time of her "retirement". What that is, we may never know. It could have been the death of a close friend or family member and that completely turned her world upside down. That could have resulted in experimentation with drugs and alcohol, which could have possibly fueled some sort of mental illness she didn't know she had at the time.
She made a tweet last week about how she doesn't communicate with her parents any more. You never hear stories about her partying with friends, and she spends a lot of time on Twitter tweeting weird pictures of herself and retweeting people making photoshopped pictures of her. I think she's lonely and add that on top of the mental illness, it isn't a good combo.
Of course, this is all just speculation. If this is one huge act then bitch betta WORK.
