I asked the same question on Discord and he said that if I was diagnosed with Autism Spectrum Disorder and Schizotypal Personality Disorder at the same time, my psychiatrist will get fired, as he said.
He thinks that I can't have both, even though the symptoms of both disorders are obviously not the same at all, even though they look similar. That is like saying I can't have ADHD, because symptoms of ADHD looks very similar to Autism Spectrum Disorder.
If that is the case, then Autism Spectrum Disorder is a developmental form of Schizophrenia.
My symptoms:
* I have fixed, false beliefs that I am better than everyone else and have magical powers based on my restricted interests
* Fantasies about being better than everyone else and having magical powers.
* Mild arrogant attitude
I have Autism Spectrum Disordeer myself
