Plenty of recent research suggests that the modality (CBT/psychodynamic) matters less than the therapeutic alliance does. Given that you might need both a more skills-focused therapy (to get strategies for getting through difficult patches in your courses, for instance), as well as something that focuses more on the underlying causes for your anxiety, the ideal would maybe be somebody who could combine a CBT and psychodynamic outlook, but I'm not sure how easy it is to find those. Although your current T might have good suggestions about that.

I have had bad and good experiences of psychodynamic Ts. Getting a T who was a good fit with me was such a huge difference that I could not quite believe it. I do think that you might be doing so much better with a T who was a better fit for you.
