Sorry that you're feeling so stuck. I can relate to this quite a bit. My T has also said that he's felt stuck with me as well, and I took it as him not wanting to work with me anymore. He stressed that he wants what's best for me, and that due to his own limitations, he was looking for other options for me. What helped was him saying that it would be IN ADDITION to seeing him, if that's what we decide, to help get me unstuck.

Maybe that's what your T has in mind for you? Something to help in addition to therapy, to help you become unstuck and make progress.....
