I don't know. I went from knowing exactly the relationships between and dynamics of everything to doubting everything, today (probably/likely because I took my antipsychotic).

It's just a model of reality like everyone has and mine isn't necessarily worse than that of others.

There's just a point in time where you trust the model of reality more than reality itself. We don't doubt it or we'll get extremely confused and so we get anxiety and we're gonna ignore more of reality to relieve the anxiety and it gets worse quickly.

But that doesn't mean that it isn't useful to make such a model of reality, right? Those who don't can't function, stuck in doubt or constant reappraisal of reality. You are too slow or to much in doubt for that to work in practice.

It's useful self-deception. Everyone does it. We are just very good at it but we consequently think we are better at it than we are because of that self-deception.

Does that make sense?
