I was also thinking that Whitney's spiral into drugs and alcohol abuse might have occurred regardless of who she married. A big part of me thinks that she wasn't prepared for the notariety and fame her career brought her. It is unfortunate she passed away. I think she was an amazing entertainer in her prime, but she single handedly destroyed her career and her voice with her vices.
You said what I was thinking, and maybe better than I did. I'll take another crack at it:
Just because a person is so beautiful and so talented, and just because her life looks so easy and perfect from the outside, doesn't mean that she hasn't always, meaning from childhood, had her quirks, demons, and warped or mistaken and foolish values.
No matter what one's color, drugs in America are always only a phone call away, and always will be, no matter how onerous, intrusive, and yes, sometimes unconstitutional the law is made to be. We all make our choice whether to take drugs, and/or which ones to take, such as alcohol, prescription drugs, pot, crack, etc., etc..
As Houston said of Brown, "We come from the same place." People are prone to look at a person, and a life, which started so seemingly perfectly, when looked at from the outside,and assume that someone else had to have pushed her into it. I figure that perhaps she didn't need much of a push, and perhaps none at all. FI, the deletorious effects of drugs don't manifest overnight; some of them take years to show up. It's entirely possible that she was doing lines when she was still in the church choir.
It's a very sad thing, in any case, but the fact that she was talented, pretty, and rich and famous doesn't really make it any sadder than the early and probably unnecessary death of any other person.
John Donne probably said it as well as anyone:
No man is an island, entire of itself; every man is a piece of the continent, a part of the main. If a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a manor of thy friend's or of thine own were: any man's death diminishes me, because I am involved in mankind, and therefore never send to know for whom the bells tolls; it tolls for thee.
