A little perspective. $40k/year is about what glassdoor suggests you should make as the manager of a 7-11. A little one.

Don't be afraid of a temporary career change. I've done it twice to save myself from burnout. We get overly attached to a narrative about ourselves as developers and become convinced that we need an unbroken ladder of the latest gee-wiz frameworks and libraries to stay in the game. Outside of FAANG its mostly not true.

But first, start telling that bully no in the most non-confrontational way you can. Take the most unreasonable demand and politely say in response "no I don't think I'm going to do that". You actually have nothing to lose.
