LT - If you haven't already filtered for these kinds of things, I would look for theoretical orientations like psychodynamic, relational, or humanist. And would steer clear of CBT or "solution-focused" therapists. You might really benefit from IFS, too.

I like the term "attachment issues," and then if you get any responses and can do a phone consult or meet-and-greet, you can talk about your anxious attachment and that you tend to get attached to therapists, but are a highly motivated and hard-working client and want to explore what comes up in the relationship, tie it back to childhood experiences, the impact on you, and how it shows up in present-day relationships outside of therapy.

I, too, don't think you'll ever get what you want or need from your current therapist. Which is not to say you haven't gotten things from this therapy. But the core needs, in my opinion, are not being addressed in this therapy.
