This. I've had mental health problems from working under bad managers, and I refuse to put up with it now. In fact, I can't put up with it - I have found that bad management leads to depression and I end up having to leave anyway.

Your manager is supposed to be the responsible adult in the room, and competent at their job. If that's not true and they're making your life worse, you have no obligation to suffer that.

If you possibly can, make this clear to your manager's manager. Even if it's only at the exit interview.
