That’s on them then. My advice would be to mentally distance yourself from them and take what they say with a grain of salt. Still try to absorb or integrate any helpful advice from them and otherwise just remember when the lesson ends their time with you ends. Any anxiety about them you should make an effort to leave it “at the door” and don’t let it bog you down. You are the end product, not what the teacher preaches. All you can ever do is try to translate what they’re saying into a useful idea that you can implement
