From what you say, I'm uncertain that you've really made it apparent to your T that you are still struggling with this. If she doesn't know you are still struggling with this, her not working with you on it is because you haven't really told her it is something you need to revisit; that's not a therapy technique. That's just a lack of clear communication. I mean, did it come up once or twice and you both moved on to something else, or have you asked her to really revisit this issue with you?

I don't think it has to be an arguement. There really is no reason for it to be. Is it possible that you have interpretted her not discussing it as a judgement that you are not "normal" rather than that she simply said what she knows to be pretty realistic and thought you were done with the discussion because you stopped discussing it? Sounds like to you just need to ask to talk about it some more.
