Good part time jobs for people with ADHD?

Okay, I'm 24 and just transfered to a university for my bachelors. Since highschool I've had tons and tons of jobs that I either quit or got fired from. The longest I held 1 job so far has been 9 months... Most have been cashier and clerk jobs at grocery and stores and shops and I haven't been able to keep any of them! Either I couldn't stand the job or I couldn't keep up. Most of the time both! I only had one job I enjoyed, and it was a summer job a few years ago. I ran a super small snack shop completely by myself. I also have social anxiety. Work fine with customers but panic around other employees or my boss. The only reason I left that job was because it was only a summer job. Not asking about a carreer, just need a part time job to help through college. Any tips for good jobs for socially anxious college kids with ADHD? Haha. Thank you!
