I feel your emotional pain my dear friend. I am very good at my job and considered very beautiful by many people. Not a good combination to accept for some small souls like your supervisor and mine.
I learned so will you! DO NOT let that b…. take over your life. You are both working there, if she was so reach and wonderful why is she working for someone else and not even for such a hefty pay cheque! She is not any better than any other employee in your company, she is just stupid small soul.
How much of your time you actually have to spend directly with her? NOT MUCH I bet. And she also has a supervisor. You don’t know what insecurities and fears she might be facing.
DO NOT let her take a second of your personal time. Be polite and professional in your work place. Do your job, no matter what she took away. As long as your pay didn’t change it doesn’t matter what or how much you do in given circumstances. And things change, she may leave the company, she may be fired, one never knows.
Build strong relationship with your family and your friends. Vent. Make fun of her, say whatever makes you happy but vent only for a few minutes and let it go. Enjoy the rest of your day, enjoy your weekend, enjoy your life. Don’t give her control, ignore her.
