Wow, that's cool that your t not only had that reaction but felt ok in telling you. I'm glad your t seems to be helpful so far.
I've had a few get that way, mostly in dealing with certain family members, but also occasionally when dealing with "the system". It's kinda nice, but I'm glad they were not all that way, and not all the time. One of my first t's told me she wanted to protect me from myself (which at the time was a good thing because I was internally self - destructive in my thinking and actions). More recently former t told me she'd work to help keep me safe, whatever it took (huge step to being able to trust her).
