How to Survive Manipulative, Shameless, Slave-Driving Boss

In my past and currently, I have the misfortune of reporting to a boss that will stop at nothing to succeed but at the same time does very little of the work herself. In other words, she relentlessly drives me to accomplish her goals with no regard for resources or rest. I am miserable in these situations and my default is to (1) hate the boss and (2) start to look for my next job. I have tried to bring to her attention the unrealistic expectations, but nothing will stop her from pushing. Is there another way I could approach this situation vs. quitting/leaving? I’m trying to not be childish, but the situations feel like pure abuse and the only wise move is to exit as soon as possible. Suggestions?
