I was not completely unaware of failing most classes in high school and having to get a GED despite
wanting to do my homework and study for tests. I was very motivated and interested in the subjects, I could just not focus enough to complete my work. This caused me to have an adverse reaction to even starting a project/task which I still struggle with today (even though it's much easier now).
So while I can of course not predict what would have happened, I can pretty safely say my life path would have been completely different had I had a chance to get treated earlier. I would have gone to college, at least.
I'm not sure what your point is.
