Thank you all for your replies.
I have realized that I feel much more than just annoyed at my T; I feel angry and hurt. The one thing that has kept me going to sessions is the connection I feel with my T and the fact that she understands me but now that idealized image has been shattered. I feel as though T is fed up with me and I'm doing therapy wrong and I'm a failure who is never going to feel happy.

T did ask me at the end of the session how I was feeling and I said I felt kind of irritated. T asked me if I want to talk about it now or wait until next week. I said we can talk about it next week. So it seems T was willing to offer me some extra time but I don't know, I still feel as though she is fed up with me.
