My T has said, "How can I help you?" Sometimes when she's done this, I get annoyed and say, "You're the professional, you tell me!" Sometimes I've apologized for this, but other times I don't. NT, were you afraid that she couldn't help you? I think it's important that at your next session, if you can, to start where you ended. For example, did she realize you had dissociated? It might be hard, but it might also help to figure out what triggered the dissociation.
