There are weaknesses in any theory. That is why you need to be sceptical of a therapist who is not willing to integrate other theories into his practice when they are needed with certain clients. Sticking to one theoretical appraoch come hell or high water just doesn't work, because you will always have clients that respond better to a different approach. The best therapists have a strong theoretical foundation that guides them that is related to their personal view of human nature and how people change, but will integrate other theories as needed. For instance, I am strongly Gestalt in my foundation, but will use techniques from Reality or Choice Theory, CBT, and Existential Theories when I need them.
The main drawback with CBT is that it deals with the thoughts and behaviors on a superficial level. It is effective in producing change, but the critics question whether that change can truly be long lasting and complete without addressing the emotional aspects, as well. I tend to agree with this. All of our behaviors, from my perspective, are caused by an emotional reaction or an attempt to fill an emotional need. Like, with OCD, behaviors develop because one has an emotional need to feel safe, so we develop behaviors that allow is to feel safe in some way. Then, these behaviors get out of control, and rather than allowing us to feel safe, they begin to create problems. Like I posted earlier that we have coping mechanisms that served us well in the past, but fail to serve us well in the here and now.
I think you have a good handle on all of this. I see nothing wrong with using CBT to change the immediate behaviors and allow you to regain some control over your behaviors. Then, once you have accomplished that, you might want to explore some of the emotional components behind the disorder to prevent it recurring in the future with different behaviors.
