When you absolutely need to make a change the way i handle it is to think of the worst thing that will happen. Generally the worst isn't that bad so it makes the critical decision much easier to make.

I quit my FAANG job with no backup in place during the pandemic and so far have done a bit of traveling. No one blames me. It's 2021, the year of the burnout. For me the breaking point was watching the movie Whiplash where everything is given for the career and thinking it all seemed reasonable. The movie wasn't intended to be perfectly reasonable at all.

I've lined up another job already but will still be a little while before i start that. I was never that bothered by unemployment at any point except that i may have had to move back to my home country if i didn't line up the next job within the visa grace period. But that's not as much of problem as a mental break. One of the nice things about having some savings is that you can prioritize your mental health now even if it cuts into your early retirement plans.

Maybe you don't get another job for a while but if you are on track for early retirement being unemployed in 2021 isn't going to break you.

You're burnt out in 2021 after the chaos of a pandemic. Completely understandable. Do what you have to do.
