How long have you been seeing this therapist? Have you talked to them about these concerns? My personal experience has been that all of the times I've gotten to the 8-10 week mark with a new therapist and found myself thinking things were going nowhere, or doubting that this therapist knew how to help me make any progress, things ended up going nowhere. And when I stopped seeing them I wished I had done it sooner.

On the other hand, I've had good therapists where things started off in a way that I felt skeptical about for the first few sessions, or in a way that was tumultuous, where things ended up being extremely productive. So a lot also depends on what makes you think things aren't helping.
