That’s basically how the end of my diagnosis went because aspects of my results were borderline, so she suggested that I just try meds to see. But keep in mind that only one type of ADHD involves being hyper. Some of us are inattentive types where our brain feels like an old 70s pony car engine, and if you pull up to a stoplight you need to keep the motor revving or it will stall. Taking Ritalin for us is the equivalent of keeping the revs up.
Great simile. That really is how it feels.
