On a more serious note; Lindsay Lohan is one of the more extreme examples of how badly a young mind can be damaged by Hollywood / Disney / early celebrity. I think I mentioned her as an example on the relatively recent thread about Demi Lovato's overdose. It's all pretty awful. These people are thrust into celebrity when they're young and showered with positive attention and adoration. They're exploited by faceless coroprate money-generators and all too often their families as well. And then when they (it seems, inevitably) go sideways, the attention stays but it turns toxic. Very few could come through something like that without a significant impact on their overall health. There are a few notable exceptions who have "made it" as adults (Drew Barrymore, Leo DiCaprio) but even they've had hiccups and to be frank while Leo is a stable adult actor he blatantly has some issues when it comes to having healthy relationships etc.

If you want a direct comparison, you only have to look at the oft-used example of Elizabeth Olsen and the Olsen Twins. The Twins got famous young and have had a plethora of mental health issues between them. Their sister didn't find meaningful fame until her early 20's, and looks extremely healthy and happy. Obviously they grew up in the same family, so there being such a stark contrast is probably not a coincidence. She got to have a normal / private childhood and teenage life, they did not.
