I'm inclined to suggest that adolescent celebrities read what Carrie Fisher is saying here, and that they would do well to heed the wisdom she's offering.
It's safe to say that childhood stars do not go through the most well-adjusted periods compared to "common" kids. And it makes sense that there's a hideous cost to the spotlight at that stage in life. Kids at that age are just then figuring out their own sense of identity. They're going through confusion enough as it is, without being called upon to be a public icon all the time. No wonder so many of them turn to substance abuse: they practically need that to feel numb to themselves.
Thanks to my good friend Eric Wilson for passing the story along :-)
