Maybe you could try having one session with T where H either agrees not to talk, or agrees to wait outside in case you need him. ??

You can still share everything that happened in the session with H, but it might be an interesting experiment to see if that would help. It is quite possible that you are stronger now, and are ready to have private sessions with T, and thats why you're feeling this way.

No matter what you decide, I would encourage you to talk with T about how you're feeling. Talk with H first, if you want, so that H can help create the space for you to express yourself.
