Maybe work on how you feel like she is challenging you? Reframe it so that she isn't more than an annoying fly is to a look. They don't get mad and waste their time killing flies, they just flick them off when they get too bothersome. So find ways to dismiss and thwart any challenging behavior from her that's the kind of thing that helped when i was finding that sort of thing hard, back in my teens lol
Just remember, that self control, self discipline, they are signs of true strength. So make them your goals, make powerful people with amazing self control, like wushu masters, make them your idols, ask yourself if they would waste their energy on something so trivial as a woman with an attitude problem (because they wouldn't, they would not give her the satisfaction and watch her self destruct or get over her attempts )
You can do this, I did, so I'm sure you can too
