Welcome to WP! I hope you find the company pleasant.
Since you are still doing the initial exploration I'll toss in a few other thoughts to make things more complicated:
-=-- Apparently there is something called "Borderline Autism"
-=-- There are other "conditions" that can be confused with Autism
I guess these are the kind of reasons for getting a professional assessment if there is any uncertainty.
After I started learning about the Autism Spectrum I (and my bride) concluded before long that I might be a "High Functioning Autistic". It was my AQ test score that added enough credibility that I pursued a formal assessment. While talking to the Psychologist who did my assessment I noted that I was pretty sure I was somewhere near the bottom of the Spectrum but I didn't know whether I was almost on the Spectrum or just barely on it. (Turns out I am on it—Level 1.)
But whether you get an assessment, or not, and no matter what diagnosis you get: Welcome to WP! It is not just for Autistics, it is also for people interested in Autism.
P.S. The Aspie-Quiz might also interest you. Note that registering there is optional!
