I am doing this myself. I turned in my two weeks' notice a few days ago

I am worried about my decision too, but I think about a few things:

- You got your current job (plus all of the previous roles), so why wouldn't you be able to do it again if and when the time comes?

- Job gaps don't look as bad as they used to. People understand burnout and being stuck in a bad job. Breaking away from those can be seen as a positive, especially if you are pursuing your own health and interests

- There's more to life than draining your useful waking hours for a paycheck at a place that offers little else. With more time and energy, you can explore interests and projects on your own terms

Best of luck in your future endeavors
