My symptoms weren't present in early childhood, I lack sensory issues, I'm able to understand subtle social cues, I don't have any of the motor issues. When I started talking with the autism specialist it became obvious really quick since it was a pretty thorough examination. I was told that autism can present itself in different ways, sometimes taking months to reach a diagnosis, however I apparently lack many of the major immediate symptoms that would often get caught as early as 5 or 6 years old.

Schizoid personality disorder, however, doesn't usually start to present until later childhood, after puberty, which makes a lot of sense because that's exactly when my parents started getting worried about my behavior and sent me to a therapist in the first place. SPD isn't well researched and can seem similar to autism. Plus I was 15 quite a while ago so maybe diagnosis methods have improved since then.

My parents initially sent me to a therapist because I was a bit of a delinquent with no friends. I also wouldn't do homework and I'd isolate myself, reading books and playing video games. Schizoid personality disorder is an odd because it usually goes completely untreated because people who have it rarely see a problem. They like being alone.
