Welcome to WP! I hope you wander around the planet and find a few areas that interest you.
I agree with not rushing into a formal diagnosis, just yet. You are young enough that it could work against you. In a decade or two, when you are more "secure" in life, however, you might find a formal diagnosis interesting. It could confirm your suspicions or, worse yet, indicate you are not Autistic...then you'd need to do more research.
And while you are sort of young to get a formal diagnosis (potential problems with employers, etc.) you might find an informal diagnosis interesting. AQ would be quick and fast, and it is not "official" so it is not obligatory to report it. (Though an unofficial diagnosis of "Autistic" could help you steer your personal research on best ways to cope with your neurodiversity.)
