I think you should always discuss what you want to discuss, it's your therapy. But maybe you feel you are fighting for control of your therapy because your T specifically said you all should stay focused and so you're "rebelling" a bit because maybe it feels she's calling the shots. I think it's good that you are thinking/feeling these things and wrestling with them, that's always good but, like you said in the beginning, you should definitely mention the struggles with your T :-)
