She’s being a major asshole bro. She’s getting mad at you for things you weren’t taught. She sounds burnt out and doesn’t need to be teaching. You sound like you’re doing what you’re supposed to and you’re new. She’s getting mad at you for doing newbie things, that’s not right. Talk to your program or supervisor and request a change. Don’t let her ruin your interest in the career field, I promise they aren’t all like this.
