Trust is really hard after only 7 sessions. I'm someone who has taken years to trust my T. So I know how you feel. If you can get the courage I would email your T and explain what is happening internally. I have done that with my T and she has told me that it helps her understand me better. You could also explain that you are not ready to "rip off any more bandaids" right now.

Another thing I just thought of. Maybe you are learning to trust her a little. Allowing her to see you when you are vulnerable and triggered can be a good sign. It might not feel like it. But I would never allow anyone to see me in that state if I didn't trust them.
