Perna gives good advice. Would it make it easier for you if T said it differently? Like, "You seem angry to me," or "I think you are reacting this way because you are angry," or "If I were you, I would be really angry," or whatever it is she means by "You are angry," which would annoy me too without more context and/or precision. Sometimes phrasing it more precisely makes all the difference in the world. Do you think she'd be open to taking ownership of the theory/observation, if that would help you examine it without feeling that uncomfortable feeling we all get when someone else tells us how we're feeling?
