I think it is fair to:

- ask your T why she wants to change direction/concentrate on other issues
- tell her your expectations
- and maybe ask her what you might expect from another T's approach

I imagine you may have asked these things already; the first two anyway.

You obviously aren't happy with this Therapist. You need not have our permission to change her. I agree with the above that you collect your ideas on paper and discuss your wants/needs with a Therapist prior to optng to see them. Good luck!
