not really too late but tbh in adulthood a diagnosis doesn’t do much for you besides give you that knowledge. you don’t get accommodations for it really, especially outside of a school setting. there’s not exactly meds to ‘manage’ autism. so unless it’s pertinent to your self, i wouldn’t both going through the expensive process
If you’ve met one person with autism, you’ve met one person with autism. No two people will be the same or have the same symptoms, so it might not be the best method to ask other autistic people to compare and contrast. If you have the means to get tested, I’d say that would be the best route. Self diagnosis can also be valid if you can’t.
