Drug addiction, alcoholism etc are terribly difficult to understand, and even harder to overcome. I have seen prisoners who are addicts, they were totally in the grip of their drugs. I don't think they could have stopped themselves, no matter how much they wanted to. I'm truly very sorry for this talented young woman. 27, world-famous and yet her life is now over. Her father, particularly, tried to help her, but addiction is notoriously hard to 'cure'. Let's not judge in any way. R.I.P.
