Faking ADHD

I just got nervous about asking my uni about ADHD screenings because I can't figure out if I'm faking it or not. I googled faking adhd and came across a 4 year old post on here about it and I had no idea people fake adhd to get meds or buy adhd stimulants for exams and shit

At least it gives me a bit more confidence knowing people fake it to get pills for energy. I just want to be seen by a professional who can calm me down and make my brain slower and more organised. I don't stop paying attention because I'm lazy, I'm just always daydreaming through classes and I'll come to like I was unconscious and have no fucking clue where we are in the lesson
