Okay this all sounds like promising material to me. You have stated a way to get to your key topics and then two ways to stay on them (bit of a script; ask t to help). It might be hard in one session to get all of the way to the depth you need. But I think that a relevant suggestion for you to consider is to say what you know you need to say but are afraid to say. This is a way to open new depths. If you can say the scary thing(s), t will be in a position to help you to understand and explore them.

For example: it might be hard to say that you don't feel understood. You might fear that t will judge you for thinking that you are not understood, and/or for wanting to be understood more. If you don't say it, though, at the end of the session I expect you will be feel that desolation of not having gotten closer to the core of your concerns with regard to that topic. When it is hard to summon the courage, remember why it is necessary to do so.
