There was a biography I read some time ago by a British Philosopher whose observations might be apposite here; I forget his name, though; if I recall it, I'll put it up. His interests appeared to lie in Continental philosophy, rather than the analytic kind.
As a tutorial fellow at one of the colleges at Oxford, he noted, that his students had or didn't have a philosophical mind; and it rarely, it seemed to have to do with intelligence; some of his cleverest students found it puzzling why some questions 'mattered' philosophically; and if a question didn't matter, then why put in the effort to understand it, or solve it; in fact, when one doesn't understand why a particular question matters, its contours then refuse to reveal themselves.
As an aside; personally, I find it a little strange that one is expected at age 10 to think about a PhD; what matters, is the why and what of it, and not the having of of it as a kind of badge; the transition, I'm sure you are aware of now, between school & university is tremendous; in a sense its a Western Rite of Passage - to put it anthropologically.
I can't see how psychosis is going to help any. Good luck with it all.
