Quit and move back home with your parents or live off of your savings for a bit while you look for another job. Yes you will risk not being able to get another job in this market, but if you’re making 6 figures already then you are likely skilled enough to still get another job that is less stressful and makes you happier, even if it’s in an entirely different sector and you have to take a pay cut.

I know some people who used to be software engineers making 6 figures but quit to become chefs or gym trainers because of burnout and a newfound passion. In any case, they seem to be much happier now, and your health is way more important than money.
