There are no promises. For the bad therapist thiss serves to protect them when they can say you failed. For the better therapist they cannot promise you will get better as it is unethical and you will keep spending money with no guarantee. It's a murky situation. I think both you and the T could make some goals to work towards and specific ways the T can help with those goals.

Therapy is far less assured than dentistry. We hope for more and shouldn't accept less than. I'm a curveball to my T. The trained things to say don't help me at all. CBT doesn't work. Flexibility is key.
