Rather than shut down and refuse to trust her, why not ask her to explain to you why she was doing that? It sounds like she may have tried but you weren't able to really hear her because you were upset. It's okay to ask again. It's okay to tell her you wondered if she was trying to upset you. Communicate these thoughts to her and be willing to dialogue about what was going on both outwardly and inwardly. I HIGHLY doubt it was being done to punish you; that would be something the mother would do -- not your therapist. But tell her that is how it felt or what you wondered; it's great fodder for discussion. It may have "felt" like a horrible thing she was doing, but perhaps if you talk about it, you might understand why she was doing it. She has never done "horrible things" to you before -- that would be something the mother would do, not your therapist -- so this a perfect opportunity to try to really talk to her about what she was doing and how you were feeling.

Speaking of embarrassment, I just found out that I have cavities.

Have spent the week in a haze of shame over it.....to the point that I wonder if I should talk about it in therapy except that I'm too embarrassed to let my T know that I have them.

So, have been doing the mature thing and obsessively googling things like "at what age did you first have cavities?".

Argh.

Heck, my family has notoriously bad teeth. It isn't from lack of care -- just sort of a genetic thing. My kids have the same issue -- again, not from lack of care. Don't sweat it. You definitely aren't alone in the cavity department and dentists see much worse I am sure.
