This was my experience with CBT therapy as well... T would actually shake his head and facepalm in exasperation at me if I said anything negative. I felt rather patronized by it. But, maybe as others are saying here that might not be how CBT is really supposed to go. Personally I did a lot better in talk therapy, where it's more about T listening and help processing. I'd definitely look for a new T if this is not going well for you.
