I have struggled with this myself with ADHD where I think my brain is great and it is society that is wrong as many of the ways I do things/see things/operate are subtly shunned by society and the way it works. Everything from the typical 9-5 (my brain works best 11-7), to most white collar careers revolving around stationary work at a desk (I love difficult mental work, but think better when I'm moving around), etc.
I don't think my brain is wrong or performing poorly, I excelled at school but did not learn much from lecture style formats (figured out how to study on my own). But I have gone back and forth with medication because it is very, very difficult to construct my life in a way that plays to my strengths when they are so different than the norm. Medication helps my brain fit into society better, but I don't think it improves my brain function.
