Dani, I feel ya! I think I've been stuck for some time now in therapy, and I think my T has reached the end of her rope

She told me this past session on tuesday that she was finding it hard to know how to be helpful. I can't stop thinking about that sentence, and how frustrating it all is. I don't know how to be anyone other than me! I feel like I should be doing therapy better, but I don't know how to do that, or what "better" even is.
Then I was thinking that what if after all this time (15 mos), it isn't some perfect "fit"? I compare her to my GP because my GP is ridiculously sweet, and young and so nice...like I just want to keep her in my pocket wherever I go. So then I think that if my GP was a therapist, would I open up more to her? And if I would, does that mean my therapy now is just crap? I don't want to start new, and if I hadn't read this board, I don't know how much I would be thinking about if we have to fit somehow. I would just be worried about the fact that I'm frustrating just because I am.
