How do you go about getting ADHD medication with no doctor?

Might be a weird place to ask, but since almost no one has a doctor maybe this is the place for such insight.

I've been rawdogging ADHD my whole life, and have had times where I've handled it better and times where I've handled it worse. I currently am stuck in a job i hate doing that keeps me constantly burnt out and it's definitely on the side of worse due to that. I feel like I barely function anymore.

I would like to be able to go back to college and finish my degree I started many years ago in order to get out of this job, but I realize the only way I can make that happen is if I am able to keep full time employment while still taking classes. That isn't going to happen unless I get the ADHD under control. I know I am in no state to succeed as I am right now.

I have never taken anything for my ADHD, and I have never had a doctor. I don't know where to even start, any advice?

(aside from get a doctor, I've been on the wait list for many years)
