Just having hyperactive, impulsive, and inattentive symptoms is not sufficient to qualify for a diagnosis of ADHD. Symptoms need to have a negative effect.
It’s important to get checked if you are struggling folks, and there are plenty of resources on campuses for these things.
PS I pinged a few ADHD academic discords; if you want to join them, let me know. There are 2 for graduate students. I am sure they would not mind.
