I'm a little confused. I think partly because I don't know what it would look like to do light processing IRRT-style, and also why you would expect her to be different when she's doing trauma work compared to not. Would you expect her to be warmer and more supportive when doing trauma work?
And did she eventually adjust after the pushing? That's still something.
Obviously, it could be that it isn't a good fit. This is the same issue I've been struggling with for so long with my T.
I wonder also (and I think you've brought this up before as something to consider) if she (or any T) can be a good fit for some parts and not for others. And is anyone a good fit for all the parts? I guess the T would have to be a good fit for predominant parts--that makes sense to me. So even if she isn't a good fit just for you, Asti, that would be enough.
Are you going to stop seeing her? What does she say if you bring up the issue about not being a good fit? I'm curious, because I think our T has managed to strike a very tricky balance of allowing the possibility that someone else might be able to help me in ways he can't, while maintaining that he's willing to try to adjust and change as much as he can and he believes it's possible for us to work it out.
