I'm sorry it has been so trying.
This may not be what she was doing, but Do you think maybe her admitting to her frustrations could be a way to motivate you to trust her a bit more? I'm sure there is genuine frustration, but most t's don't bring up things like that unless they believe it had a chance of being a push towards a breakthrough. I think it at least might warrent another conversation. I have had t's tell me things that upset me quite a bit initially. I agonized over them a whole lot more than necessary, but that's just the way I am. In fact, a similar thing happened with me and my t earlier this week. I was able to write my thoughts out, and eventually able to communicate with her about it (I did very little actual talking because it was very difficult). What she said was meant to bring my attention to things that were problematic and frustrating barriers to therapy. my upset over what she said promoted a change in the way things are going. It's not the kindest way to do things, but sometimes clients have a way of ignoring the kindness (at least i do). It's also not meant to be detrimental, but to "shock" us into some sort of motion again after We start to stagnate. Keep in mind, this is just a theory. It still may be worth talking to her about it... change, attachment, and trust are all very risky. It's understandable to sabotage it at times. I think I'm the queen of sabotage...

Good luck. (Hugs)
