How the FUCK do people get diagnosed with ADHD?

I go to a psychiatrist because I'm failing Uni and tell them I can't focus, they say I have depression and give me Wellbutrin even though I am not depressed. 2 months later I come back and they raise the dose and say come back in 2 more months.

Literal shit eating 12 year old kids who play Fortnite all day can easily get an Adderall script but an actual college student who is trying to get a degree can't get shit. Fuck doctors.
