One thing that I found really helped when my therapist was pushing me too hard was to tell her just that, that I want to keep moving forward, but I need a break from the pushing first... I used the example of feeling like I was running a race on a broken leg.. I can get to the finish line, and I will, as long as I have the opportunity to sit down and give my leg a break every once in a while... I don't know if you would be able to share with her how that kind of reaction would affect you or now, but it may be worth a shot..

It may also be worth something to bring up your other feelings toward your therapy, and your fears about it with her. If nothing else, she may be able to reassure you that it is worth it, and help you find a way to look at it so that it has a better chance of working for you.
