I'm eight months in with my T, and I think a lot of these things come down to experience. The more time you spend with your T, the more experience you will have of her listening, not judging, being there and not dumping you. I'll talk a bit, then freak out a bit, talk a bit, freak out a bit...

At seven sessions in, it's early days. You're forming new habits with your T: talking about things you've kept quiet for a long time, breaking rules that exist within your own psyche, trying to be seen and heard when you've previously been invisible. You don't have a template for this, it's new and scary.

I don't know what diagnoses fit or whether your T will tell you (depends where you live, what kind of T you have, etc, e.g. mine is in private practice in the UK and does not have the power to dx me). Can you ask what your T is thinking? YES, and I whole-heartedly recommend doing so.
