As a fellow autist i am not sure if i would handle such a chain of events so well as you did.
I actually have some context for autism-schizophrenia.
Both medical disorders as well as adhd/add/ocd/dislexia/bipolar are all part of the neurodivergent family,
Therefor its common for overlap between these conditions and for different medical diagnoses to be more common in a single family tree. You may have (had) a schizofrenic family member and to some your autism resembles parts of it.
None of that matters to how your family treated you because even if you did have dillusions or psychotic feelings they are still no reason for forced therapy. These conditions, are very misunderstood and the only person that can truly know if they need help is the neurodivergent person themselves except maybe if they cause proven major harm.
