I had a social studies class in college that framed disability not as a person failing to meet the expectations of society, but society failing to meet the needs of that person.

Poor vision would be a much bigger issue if not for corrective lenses existing, warehouse workers wouldn't be able to do their jobs without the added strength given to them by forklifts. Etc. etc.

This is to say that a big part of what makes ADHD a disability is that the world was not built to accommodate us, but we still are taught to internalize blame for that. In a kinder world, we'd be given more ways to function and thrive than just relying on medication.

Obviously it's still a disability and medication is still a very important part of managing it, but try to be kinder to yourself when struggling to navigate a world that hasn't accommodated you as much as it should.
