Ah, I’m in this boat. My advice: stop trying to force a job. Explore your interests until you find a spark. Talk to a lot of people about what they’re up to. Maybe you want to go on one of their journeys for a bit.
Also, if the guy paid for an extension pass and was auditing courses "officially", he's well within his rights.
I was really worried about what I would do AFTER so I just kept working a day job even after I made FU money.
The difference was that I started working for different reasons which was meeting people and learning about the problems they faced.
Meeting new people and deepening relationships with people I already knew has been great for my mental health too.
It’s given me cool things to work on as well.
