HELP MY COWORKER IS SABOTAGING MY LIFE AT WORK :/?

I've dealt with this more than once at a job. People are telling you to go to the manager, the supervisor, the yada yada yada...look, that never works. Superviors either don't want to be bothered by these types of problems or they love drama themselves sometimes. Instead (and this is hard), manage yourself. You cannot control her...can't control the followers. You control yourself. You are there working. This is a job if not a profession. Your opinion of her stays at the door. Decide YOURSELF that you will remain a professional despite whatever is done. Their opinion of you is none of your business and feel free to repeat that to whomever wants to tell you what's been 'said'. You focus on your work, get GOOD at what you do, make yourself a stellar employee and as hard as it is, ignore the attitude and the drama.. Make it clear by your words and actions that you will not even entertain the thought of anything outside of your position description and duties as it pertains to this woman.
