I had a psychiatrist send me off with the helpful suggestion to start working out, I was a lifeguard and literally had to work out to keep my job. He also told me I couldn't have ADHD because I'd graduated high school, without checking if I actually had. Like I did, but he just assumed that. The kid who showed up twice a week and turned in work never also graduated. My school had an excellent graduation rate, just ignore all the people who graduated unable to read past a 5 year old level.

I'm still undiagnosed, though not for lack of trying. One doc wanted me to stop literally every medication I was on for like an entire month "to get a baseline", and when I refused he prescribed me something I couldn't take anyway, and I never went back. I'm chronically ill, that would literally land me in the hospital.
