Welcome to the forum Aaron. I’m a parent/caregiver to a SZ son who is 19. I don’t this question is in my wheelhouse but just wanted to encourage you that you’ve come to the right place. And I’m glad you are attempting to understand versus just running away.
Also, search for this thread. Good insight: G/F of 7 years most likely Schizophrenic w/Anosognosia
Again, Welcome.
