Demi Lovato's career is suffering because of her personal life. It is sad and she is having it rough. Along with an eating disorder, she has confessed that she also has some pretty serious mental health disorders too. She explained that she in her career in early in her life, actually on the show Barney and then working for Disney.
She grew up with a father who had some big problems too. The stress of always having to look and act just right because she was a star took a toll on her. She said she feels like she lived too fast. Also the emphasis placed on her body and her looks pushed her over the edge with her eating disorder.
She has had substance abuse issues too. Sadly, that is how it goes for many child actors. And, sadly as well, the fans and those who like to watch things she is in can't just sit around and watching nothing while she works on her personal issues. Life goes on for them. Hopefully she will recover soon after getting the help she needs.
