What if I am on Adderall, under doctor's supervision, but I don't have ADHD?

Two doctors I've been to have told me that I need to get an ADHD evaluation because they're convinced that I had it when I went to complain about other stuff. I took the referral and got the evaluation, and I felt as though the psychologist was just trying to find as much evidence to pushing the diagnoses rather than not. I got prescribed Adderall and was told if it worked, then I had ADHD. Well... It works.
But then I read that anyone can benefit from Adderall.
I perhaps do have ADHD (all evidence suggests I do, I guess I'm just sorta in denial, not wanting to think there's anything permanently wrong with me), but hypothetically speaking, what if the diagnoses was incorrect and I took it for a long time, Would it be problematic? (I got asked to take an EKG before taking the drug and everything seems to be fine)

i'm prescribed adderall because my psychiatrist just likes to find problems in people and prescribe medicine (maybe he makes more money that way or something, lol). i guess i have some symptoms of ADD, but i don't think i actually have it. i take adderall to study because it helps me read faster and remember more. i'm 17 and i've been taking it since i was 14 or 15.

i think adderall works for everyone. i have a lot of friends who don't seem to have ADD and aren't prescribed adderall who sometimes take it for a big test, and it works for them.

adderall won't cause any long term problems, but be careful not to become too dependent on it if you don't really need it. this happened to me, and now its hard for me to study at all without it. also, your tolerance to it will increase after you take it for a while. i used to only need 5mg, and now i need 30mg.

If you took ADHD medication and you didn't have the disorder in question, you'd become very energetic and jittery. Likely more irritable as well. Basically, taking Adderall when you don't have ADHD will give you the symptoms of ADHD.
