Maybe you do, but do you really want to get on medication for a thing you aren't 100% you have? Do you have health insurance? Reason I ask is that ACA plans all have to treat mental health like normal medical coverage, so there is a good chance you could go see someone to talk about whether you may or may not have ADHD and other stuff for cheap, and if your plan doesn't have good coverage you could maybe look into switching to one that does once open enrollment happens again.
