what is wrong with her?

what is wrong with her i don't understand. she nitpicks and gets mad at every little thing i do or say, it's like power trip for her to make me scared to talk to her. like the only time you pick your words carefully is when you are talking to someone you don't know, or someone you're afraid of, why would she want that, to be regarded as unapproachable. she was right, she is a bully.
