I would kind of say "Living life without intervention can be dangerous".
I was about 40 years old when AS was recognised in DSM-IV, so I was never going to be diagnosed when I had my most significant emotional and social problems in my teens and early twenties.
But I did get intervention.
I fell in with a rehabilitation group, where I was living with a couple of families that provided structure, emotional support, living skills over a 5 year period. I even underwent a five-month live-in program of structured activities and social and emotional skills with about a dozen other adults. This program wasn't designed specifically for people with AS (which was effectively unknown at the time), but was for anyone who "couldn't get their life together" - drug addicts, people with moderate anxiety or depressive disorders, and so on: lots of structure and regularity. It had physical exercise, healthy eating, work programs, structured social interaction programs, counselling ... and it all helped. Somewhere during that program, I realised that my problems had not got any smaller, but my capabilities had grown enough to manage them. I wasn't being snowed under all the time by life.
And I am still undiagnosed (or self-diagnosed), having never been to a psychologist, psychiatrist or neurologist in my life (because it was much less common back then - I had never heard of anyone I knew going to any of these professionals, and would not have known how to do so myself - or felt up to meeting a total stranger about deeply personal issues).
Intervention, I think, was the important thing for me; but a diagnosis was impossible for much of my life. Not saying that anyone else will have the same experience.
