I firmly believe that this women was used. Yes she had money and yes she had many, many personal problems but I sense that she was chewed up and spit out by the "entertainment industry" and the public in general. I could just sense it.. this woman lived in sadness. Her more recent time was full of pain and heartache, and that makes it that much clearer to see why she might have taken her own life (which I'm almost sure of).
She is in a place now where judgements are never made, tears are never shed, and despair unheard of. I am positive that whatever pain, despair, and heartache she felt during her final moments have been replaced with love, laughter, and content. She is home now. Let that be enough.
