Masking may come easier to someone who is fully an adult and had to adapt to be able to survive. One doesn't keep a customer service job by being unmasked. So perhaps that is "better"?

But on the flip side, growing up means more responsibility. Failing a final in high school says I get a C- for the year, big whoop. Failing a final in college means I get a C-, means the class doesn't count as a prerequisite, means I have to spend more money to retake the class.

Forgetting to hand in an assignment doesn't mean much in school. But forgetting to pay a bill has much bigger consequences (especially if you do that ADHD thing of stressing about it every night and day but being unable to actually do the damn thing that would fix it :) )
