Googley, I understand exactly why you are upset. I have shown T some things and he usually asks for a copy, which I refuse. As time has gone on, I've been able to ask him why he wants copies, and to find out the security of these things (i.e., that he will not show anyone, ever) and I have become comfortable enough to, occasionally, let him keep a copy. But it has taken ages to get to this point of trust.

It sounds like you felt her bringing up the insurance thing was an effort to persuade you to give her a copy of the writing. Maybe that was her intent; or maybe she was trying to reassure you that it would be safe from prying eyes--but that's still a nudge in the direction of letting her have a copy of it. Those of us with trauma histories can be especially well-attuned to any kind of pushing. She may not have realized how her comment was going to be perceived. She needs to hear how you experienced that moment.

I suggest you talk about this next time. You don't have to take the writing, especially if not taking it will help you feel more in control. But this is an important thing to talk about. Figuring out when you feel safe enough to share something like that writing is part of the hard work of therapy for trauma.

For me, when I feel angry at T, it helps a lot to write through it and do some processing of my feelings before I see him. It helps first because then I can put it aside to get on with the rest of my boring non-T week, lol, but also so I know clearly what I want to communicate next session.
