I have autism and bipolar 1.
Autism does not have pills.
Circumstances of your birth have no causation to autism. Neither to circumstances of your life. All sorts of people have autism from all walks of life.
A reason to research and understand one's own autism is to recognize what in your life overwhelms you, and how to structure your life in a way that is comfortable and functional to you, without a judgemental neurotypical lens. To embrace who you are, rather than try to force yourself to be something you are not.
You can seek a diagnosis if you wish, but I can't tell you if it'd give you what you're looking for.
I learned about my conditions through following various mental health communities for years and seeing what had commonalities with me through the fun lens of dank memes. I also learned a lot about medications, warning signs in therapists, and I learned what mental health conditions I don't have. Can't say if that'd work for everyone, either, but I did learn a lot more from the communities directly rather than reading the clinical book definitions.
I uh. Have no idea if this fulfills what you need, exactly, it's about a very specific facet of autism, but I've read this book and found it helpful for grounding how to navigate, self-care especially:
Unmasking Autism by Devon Price
I knew a lot of the information already, having built a lot of similar systems myself, but I feel it helped me feel less completely free-floating, based entirely in my own life theory with no contemporaries. I did learn some new things, as well, especially about wider context, safety, and how the stereotypes don't serve any of us all that well.
It is... a bit of a narrow focus, I don't know that it would give much information to those who aren't high-masking, I don't know that it would do much for someone who absolutely has to mask for safety. But if you struggle with high-masking and think there are probably at least some areas one could learn to let go, it is a decent reference. (Such as the case of me, who struggles with masking even in spaces I am completely alone, and suffering greatly because I have a lot of trouble letting go of what I "should be doing," and ending up perpetuating unwitting and unwilling violence against myself. Still working on that.)
I hope this might be helpful information, even if it was not precisely what you were looking for.
