You left your job because you were burnt out. I think you should also ask yourself what happens if you start your own project and get burnt out again before making any decision, and/or what can you do next time (either with another job or your own project) to avoid burn out.
In your shoes, I'd first get a job, possibly more sustainable than your previous one. Then I'd start working on my side project trying to make a second income stream. BTW, startup school is starting soon, you should definitely join in and test yourself for 10 weeks.
I feel the reason for burn out was because I was working on something I don't care about. I don't necessarily think the work was extremely demanding or anything. The problem was forcing myself to work on something I don't find meaning in.
Yeah, for my next job. I'm definitely gonna search for a company that has a mission I believe in.
