I hate to use the word blame here, but her no account loser previous boyfriend, Blake Fielder, introduced her to drugs and started her down a path of destruction. Add a life long issue with depression, and it was a tragic, yet inevitable recipe for death.
Lots of people go through worse with none of her resources to get better and end up living solid lives. She could have made drastic changes and ended up getting not just better, but reclaiming her career in full. I thought that a huge part of rehabilitation was to end up making substantial changes to your personal lifestyle, leaving behind these toxic influences. If she had finished a tour, fired the hangers on, and then started unloading a lot of her lifestyle, she could have saved herself. Seh then could have gotten medical treatment and then ended up with better health and then a huge comeback.
Throw in a bunch of interviews, and she would have been better and back and in a stronger position to end up being a huge role model and moving only upward and onward. It would have been difficult, but it’s that very difficulty that would have been so inspirational.
