Building on this and replying to OP’s more specific question.
It’s an interesting situation (not just for op but for all). Sometimes autism presents challenges in someones life that are directly related to the autism and sometimes they show up as more second order things.
Re: building flash games as a child and not getting understood by piers and teachers. As a child, we (all humans) make meaning out of the world through an ego centric lens. We also rely on our caregivers and peers to help us make meaning out of emotions / situations. If you don't have that around you, a child naturally takes on an internal view of “something is wrong with me because i like coding flash games and they make fun of me for it”. Given the question, Im guessing you didn't have someone in your life that you could show those games to and have mirrored back the natural excitement you felt internally. But if you took the same child in that same situation and surrounded them with other children who liked reading encyclopedias and caregivers who knew how to support that interest, the child wouldn’t turn into an adult with a bunch of traumatizing memories.
Lots of ways people deal with this childhood trama. Some don't. Some find friends who experienced something similar, some find therapy, some grow out of it. I saw a kid who used to bully me deliver me pizza, which felt good.
There seems to be something in the autism brain that really likes to understand why things happen. Which is useful! It’s cathartic to understand how brain works and why things worked that put you here. But remember that emotional problems need to be solved at the emotional level. If you feel like a rational person without emotions, thats ok too! But it’s also an emotion! Ask question if you want me to clarify here.
As far as a concrete day to day things, this really depends on how on the spectrum you are. If its 0 - mild: my best advise is just realize that your brain works differently and thats ok. As an adult your job isn't to be someone you're not, but it is to support the inner child within you. Hold space for the grief of the life you might have had and grace for the ways in which you don't live your perfect life.
