If a disrespectful causes you to react than you have the problem not her. We all mispronounce words and we all make mistakes. If you mispronounce a word, correct yourself (if you feel) or continue talking. Her face making shouldn't concern you. You can't control face making, it's her face and she can do what she wants with it, if it doesn't harm you physically or change your outcome in life, don't let it bother you.
If you just continue on and not let it bother you over time she will notice and most likely stop. Most people do things that they know people react to. Stop reacting!!!
You got this. If you all recon, than you can voice you displeasure with her face making and how it makes you feel.
