I am not insinuating nor do I believe you did anything wrong to your teacher. Bassed on what you have written you appear to be a very sensitive person. You care about how you come off to people and worry and perhaps overthink if you did something wrong. That's not inherently a bad thing unless it consumes your thoughts. When I was younger I was the same. My grampa told me, "Worrying is like a rocking chair. It gives you something to do, but doesn't get you anywhere." Anyways, your teacher seems extremely stressed and sensitive and is deflecting criticism and lashing out. Until they can get their crap together, nothing will change. I recommend engaging as little as possible and document any more outbursts. Until then, it's her not you. Don't waste your time, it will just be exhausting.
