Because we didn't have as extensive diagnoses or therapies back in the 80s compared to now, I had my own phase of wondering what was wrong with me. There weren't any peer or adult role models available to me that really related to my experiences. As a result, there were some difficult years in there...but also, I had to find my own resiliency and ways of mapping my worldview to other people.
Fast forward 40 years. I am conflicted about which is better: to be left to figure it out on your own, or to have a support system that is (at times) overly biased towards leaning on the diagnosis as the explanation. But I can say with high confidence that at least for the coming-of-age years of my child, I am far more thankful that his experiences are different than mine.
"Being a human" is grossly inadequate as a lowest common denominator definition of the needs and experiences of children. Even as broadly discussed as it is, it's still only ~11% of US children and that's still a challenging hill to climb if their peer culture doesn't provide some sort of explanation or incentives for understanding each other.
