I have had maybe 8-9 therapists. I have seen three therapists longer term (a couple of years each). One was decent and the other two were great. Of the great ones, I felt a connection with one almost instantly and kept the strong connection the whole time we worked together (until I moved away). The other great one (the one I see now) I felt was highly skilled and helpful all along but didn't feel much of an emotional connection until fairly recently. The rest I saw for a range from one to maybe a dozen sessions, and they were all pretty forgettable.

I think it's okay to keep looking, especially if you don't feel like you're getting what you need. With my two great therapists, they were great for different reasons and helped with different things in different ways (they are extremely different people!). But the key is that I felt like the sessions were worth my time and energy. With the forgettable batch, I liked some of them and wanted it to work, but ultimately didn't take very much away from our time together. And I think it only takes a handful of sessions to know that the "fit" isn't quite there.
