What is your definition of getting better? If you are using someone else's definition, I think it could make perfect sense to not want to get better, since getting better might be being defined as getting closer to how someone else wishes you to be, not how you wish to be.

I have no desire to get better as some people might define it.

What would you like from therapy? How would you like to feel different than how you feel right now? How might therapy possibly help you do that?
