Of course it is true that as a child he was essentially exiled from most other children, educated mainly on set with the other child actors. He has said himself that he is not very gifted academically. Many other child actors who have made far less money and been less famous have not enjoyed very happy later lives.
The big problem, though, is that the part he was playing was of a powerful person who could manipulate reality, behave in a way which transcended gravity, for example. So he has rather less grasp on reality than if he had been playing a child in a ‘normal’ school setting, coping with the realities of, for example, working parents on low wages.
Peter Pan, really. Who never grew up.
