I can understand why that would make you uncomfortable. But my attitude is quite the opposite. I love that someone in the world knows me and my story. It makes me feel less alone. And I would love it if my T would talk about me with people (anonymously of course). It would make me feel like she cared enough to share my situation with others and that she's thinking about me. I guess it makes me feel good that she has all this information because I trust her. If I hadn't reached that trusting stage yet, I might be worried like you are.
