Have you ever walked away from a job? It's really hard to do.
When I was young I detailed cars for a small dealership with 3 owners. It was a hot summer day, no AC in the shop, boss wanted me to get a car detailed in 2 hours. Kept asking if it is ready, and at some point he started screaming at me.
I literally said, "Fuck off man, I'm done, you can do this shit yourself". It was the most liberating moment in my life. Other owners called me and asked if I would come back, that the other guy was sorry. I didn't.
Today my emergency fund will cover 2 years of living expenses, because I never want to be stuck working in a crappy environment.
Of course, and of course. But (I presume) the OP works in the same industry most of us do, and that getting another job has been incredibly easy for more than a decade.
No regrets.
