Yeah, you keep telling yourself that. She lived the dream of a gazillion women in the world, so yeah. You keep telling yourself that is what made her unhappy.
I'm guessing her problem is what quite a few very beautiful women have. They get everything too easy so they get lazy, and once money stops flying into their mouth they don't have a clue how to look after themselves. Hardly reason to feel sorry for her. But I'm just guessing. I have no idea, none of us do. She might have had serious mental problems, she might actually have been happy. We'll never know. All we have been fed is the media image of her. We're all just guessing.
