What is the best therapy

I’ve had 15 CBT sessions and during the last one, my therapist said it’s no longer seems to be working for me and perhaps we can look at the other options…. She’s right, it’s not working for me anymore (it did at first as I was highly motivated and just wanted to try) but now I feel like I just stopped, basically all we do is set a goal for a week and then we see if I did it and how I felt eating it. I feel like I need different kind / approach therapy. Maybe anyone has a good experience with different therapies so I can ask at the hospital to try that out..
