I was in a very similar boat, I think everyone has a difference sense of responsibility around work and life. At some point I decided that it was time to just embrace the fact that time is limited. You can always get a job and always make money, I don't know what you (or anyone) does, and it might not be the salary you make now or the dream job you have/want but ANY capable person can make some money.
In my case I decided to take the break, the only difference was/is, I was thinking I might be close enough to my FIRE numbers so my break turned into FIRE. I sometimes question it, or think I'd like to do something PT but now, given COVID, not even trying. However over the course of my 'career' I'd taken a couple of 4-6 month breaks and my suggestion is if you can afford to do it, go for it, it might give you a new found energy.
