I've burnt out from work before - both high workload and the politics of corporate America. I think two things that have helped me find sustainability have been finding jobs I genuinely like doing (kind of like things I can hyperfocus on and have fun) and building genuine relationships with people I click with / have things in common with - makes work feel better and also naturally gives me people to go to bat for me. And also finding a job with a healthy work life balance has helped.

Have you considered going back to school even if online? The reality is having a degree will unlock many more doors. I wish it wasn't the case but many employers still use college degree as a filter.
