I don't think you mean to be, but saying these disorders can be fixed with some fresh air and exercise doesn't match with reality.

I have ADHD, exercise and fresh air didn't fix it. I even got rid of my smartphone and home internet connection for 6 months to try to improve my focus. That didn't help either. After years of dead ends, getting a diagnosis and medication is more or less the only thing that has allowed me to hold down a job and live life.
