It sounds like you are not getting the REACTION that you want from her. You are looking for something from her, could you put your finger in the neighborhood of what that is? Or is it that you feel like you are going downhill and you can't stop it, and you're worried what happens when you hit bottom? Both of these may be off the mark; that's just my impression from what you wrote.

But these questions would be great ones to raise directly with her. Please don't email them-- I think the likelihood of getting a therapeutic response via email is really quite slim, unless your T is particularly skilled at doing therapy by email-- which is not a claim I've heard any T make.

"I feel like maybe there is nothing you can do to help me".

"I feel that maybe I am expecting too much from therapy."

Just be as direct and clear as you have been here. If that doesn't lead to any resolution, maybe you need to ask her what else you should try in addition to therapy. Or maybe you need a new therapist, and she can help you with that.
