Andrew G has some great points.
With this professor, what are you attached to? Probably a good grade. Or you have an emotional attachment to your work or how you expect to be treated. (or something else?) I apologize for getting zen here, but if you let go of whatever is causing the problem, it helps SO MUCH! Work hard and let the harshness roll off you. Easier said than done! Let go, breathe, let go… Good luck!
