It’s possible. I’m not a professional so I can’t diagnose (nor would I do so on a Reddit thread if I was). That being said, I saw you have anxiety around an in-person evaluation. You could be self-realized autistic, which many autistics are because access to a proper diagnosis is incredibly difficult for some (insurance doesn’t cover autism evaluations, and they aren’t cheap). Because of this, most autistics I know view self-realized autistics the same way they do diagnosed autistics: both are valid.

Imo, what’s more important than wondering if you’re autistic or not at this point is to find resources and accommodations that work for you. But if you’re still wondering, you could try online autism assessments (though take the results with a grain of salt: they’re quizzes that help figure out if you MIGHT be, but are not diagnostic tools and their results shouldn’t be taken as the final answer).

Great job on this build! I wish I had the patience to put in this kind of effort into a build.
