This one speaks to me on multiple levels.
It's a reason I dropped my scepticism of medication and went to get a diagnosis and subsequent prescription. I am glad I did - and that it worked first try. (It's not guaranteed anything would, depending on unknown factors and probably autism also influences the effectiveness)
I can confirm: At first, it really feels that way. But now, half a year later, it balanced out a little and I am only medium fast. Still - much improvement compared to before.

Valid, too, of course.
I am speaking from the perspective of a late-diagnosed adult. With kids and teenagers it is difficult to gauge the cause of mental health problems as well as the effectiveness of treatment. You better find a doctor that knows what they're doing... Sorry yours didn't - not all of them do, unfortunately.
