Hey there, sorry this took so long to answer. I usually only have time to get on and type real answers at night.
A good way to find out is a combination of a couple tests. The RAADS-R is the most accurate known autism test. It is known to be over 80% accurate by itself. Here is a free one that doesn’t require registration: https://embrace-autism.com/raads-r/
I would combine that with this one, especially if you're high-masking (this would feel like doubting you're autistic too, but the doubt itself is not a diagnostic criteria): the CAT-Q is a good test to identify camouflaged autistic traits that you’ve learned to hide. This one is also free from the same place: https://embrace-autism.com/cat-q/
BTW/FWIW if you’re 18+ there is less reason to get formally diagnosed. University of Washington did a study some time ago which found self diagnosis is rarely wrong. The paper states, "We believe that if you have carefully researched the topic and strongly resonate with the experience of the autistic community, you are probably autistic."

As always, feel free to ask if you have questions even if it's not autism stuff. No promises but I'll try my best. :) It’s a big world to navigate if you're new to it.
Thanks for the kind words, I'm trying my best! Remember just saying something kind about something you like is also a rare art, and I hope you keep that up!
BTW, you can "follow" people on lemmy by shooting a message (even if it's just says "Follow" in the message) and then just visit your sent messages and look for the ones that say "Follow" and click the user you sent them to. Not perfect but it's something.
If not, I'm sure I'll see you around. Cheers!
