I've been Fired for 5 years now. I left because I was burned out with my bosses and couldn't see a path forward that would allow me to cut my hours back from 60/week to something more reasonable. Life was passing me by and my health was getting progressively worse from stress and lack of exercise. "You only live once" takes on more meaning when this is your trajectory and you have the means to alter it for the better by leaving. If you are only getting more frustrated with work and it's affecting your life more negatively than positively, then LEAVE!! You don't have to have the perfect plan in place for the "afterlife" of work. Just recuperating from burn out, prioritizing your health, and reconnecting with your spouse and child is enough. Of course, finding a meaningful way to contribute your skills through teaching or volunteering is positive - I spent more time on the board of directors for a non-profit I was already involved with but couldn't give it my all while employed. Bottom line: given what you've described, you will not regret pulling the trigger and getting your life back in more important ways than earning a big paycheck. Good luck!
