I had some questions come up for me when I was reading your post. Is your therapist a counsellor/psychotherapist? Or something like an occupational therapist? I don't want to intrude on your privacy if you'd rather not say.
Can you say anything more about the rehab you have? Is the rehabilitation therapy very specific to the disability - is it a really necessary thing that your T has to have in depth knowledge of the issues you face? Or is it talking therapy that mainly focuses on your emotional/psychological life and how it is affected by the disability. Could another counsellor/psychotherapist help you if they were willing to learn? Or is it better for you to have access to someone with specialist knowledge?
Probably it would have been good for her to raise the issue when you started working together again - but she may have taken her cue from you if you did not bring it up.
I suppose if it felt appropriate and you want to try to iron this out with her you could feel out her readiness to talk about the subject again response by using a script like:
"T, there are some things about our work together that have been bothering me. They've been on my mind a lot and I think it would help if we could talk about them"
You'll probably get a good idea of how well this might go from her response.
I suppose it's also worth thinking about what you would want from that interaction too, if you did decide to talk about it?
If you're experiencing anger and it's not going away, I wondered whether it's possibly related to other pain/vulnerability that's hitching a ride underneath the anger? Is there something about her expressing such a different opinion from yours that really hits a sore spot? Does the anger feel like any other anger/vulnerability you've experienced before.
I know that I once blew my stack at a male counsellor when I wasn't feeling heard and eventually realised the anger was down to not being heard or protected by one parent from another. I was angry on one level because he was being an ass (in my opinion!) But there was a whole world of anger and pain linked into that incident that came roaring to life.
If you don't think you're ever going to be able to talk and get a satisfactory response and your work together will continue to suffer, then I don't think it's wrong to switch to another therapist. I suppose it's worth thinking about again if this is not a counselling profession as such, then what you might do if you run into the same issues.
I know that I tend to spend a lot of time early on with a new T working out boundaries and expectations up front and these keep getting revisited in-session. I find it really helps us both keep on track to talk about how the relationship is going.
Hope that helps!
