I would have thought schema therapy was perfect for someone with abandonment issues. However the CBT side of things really isn't suited to the relational side of things. There's nothing to say you couldn't try psychodynamic and go back to her later.

Also don't put too much weight on what she said about not thinking highly of psychodynamic therapies, i think most T's have a bias towards their own type of therapy and it's a bit of a competitive thing with some therapists but not taken seriously.
