One thing that helped me work better with my T was when I imagined she was sitting next to me as I talked to her, like a friend or confidant would, instead of "across" like a teacher or "other" person. It was easier for me to talk about difficult things that way.

It sounds like you're getting better at experiencing the triggering times; they won't just get better suddenly but you'll be a bit freer in feeling and ability to talk each time they happen, kind of like how it happened after seven sessions with this T which took over a year with the last one.

You have to explore the territory of the triggers, play with the wires :-) over and over before you can see their different colors and know which ones to clip to disarm them forever. I bet you'll get there, sounds like you have a good start working with this T.
