Worst: work caused me to lose passion, be stressed/really close to burnt.

Best: I resigned

Just do passable grunt work mate. Or find another job.

I'm just about here, still love programming but the overtime is draining me.

today', I resigned too and now I'm in a loop of stressed feelings.

Definitely feeling the first one. In the same place at my job currently. Finding it harder and harder to muster the motivation and it's affecting my productivity. I am biding my time to move jobs but it is pretty inevitable in 2021 I think, just can't be bothered with the recruitment/application circus yet.
