Hangingon- From the sound of your emails it seems like she really cares and has a good sense of what it is going on with you. Im sure she will bring it up and you will feel better. From her response it sounds like she wants you to tell her what you think/feel. That is a very good thing!
I know that feeling when they dont give us what we need from them at the moment. Your t knows you took the plunge- you were honest and you even somehow communicated to her what you needed in your response back to her. That is very brave.
I hope your session goes well- I think it will. She sounds good.
Im thinking about you, too.
