I'd be annoyed with your therapist too. What he said seems invalidating but also just childishly simplistic or like someone phoning it in.

Part of the reason CBT claims to be more "empirically based" is that it's just plain easier and quicker to collect the data. When it does work, it tends to work quickly, though I personally think its effectiveness is limited and can be superficial. I have found it useful as a self-help technique but strict CBT therapy seems like it could be done just as well by a well-trained robot. And actually that's probably what insurance companies like about it. It's simplistic, well defined, quick, easy to collect data, and treats everyone -- therapists and clients -- like cogs in the machine. Very corporate-friendly.

I would say that if CBT has not helped you much after a year, that it would be reasonable to try something else. It's in no way your fault that you haven't seen relief yet, different kinds of therapy help different people. Perhaps the most pro-active step you could take right now would be to consider a change.
