I would keep it as specific as possible, as in: "I emailed you last Wednesday and asked you X, Y, and Z and got no response and that made me uncomfortable, like you did not like my emailing." Hopefully she will say: "I received that email but did not have a chance this week to reply but we can talk about that now if you'd like" instead of, "Oh! I don't think I got that email" or, "I got the email but did not realize you were asking me questions, just thought you were using the email to ask yourself those questions or, this part where you said, 'I think I know the answer. . .' I thought would be better if you worked on that yourself instead of giving my opinion."

Why your T does/does not answer may not have anything to do with you? Or, her feelings are probably not going to be what you are afraid they might be; that's your head doing a number on you rather than anything coming from T.
