Demi Lovato was a child star that had everything going for her. She had both a successful acting career and a successful singing career. However, it was too much for her to handle all at once. While on tour with The Jonas Brothers she suffered a mental breakdown. Her family held an intervention and had her removed from the tour and into a treatment facility. She got better, dropped the acting career and decided to just focus on her music.
