These are all excellent questions, Ad Intra. Therapy shouldn't be re-traumatizing, and I think it would be prudent to go over these and any other concerns you have, in person, before starting the narrative. I'm sure your T will be obliging and appreciate your help in setting up a safe and supportive environment. If it were me, I'd bring this list to your next session and go point-by-point.

Good luck & take care.
