They are actors, young people paid to display exaggerated emotion while living in a world that values youth and appearance over everything. Then we ask them to constantly adopt new characters and shower them with on-again off-again false praise based on whether or not they are working on a given day. Frankly, i am impressed that any of them manage to walk away without profound mental health issues.

My impression is that there's not much causation from being an actor to mental fragility. It's the other way around; the pool of people who make good actors is already prone to mental fragility before they become actors.
