A source told Radar "Her friends and family became increasingly worried that there might be a serious problem with Selena. Particularly, her parents. The partying was, at times, wild. They wanted to help her -- and they very much encouraged her to go to rehab. Others very close to her also urged her to seek professional help."
Another Source added "t's important to remember that Selena had worked in Hollywood non-stop for six years. She was exhausted. Selena was smart enough to understand that she needed to take control of her life.It just got to a point where she needed to get out of Los Angeles, get away from 'the scene' and the pressures of Hollywood, to also get away from those who had, admittedly, become a bad influence on her. Selena needed to take the opportunity to work on herself. She realised she needed help."
