Mia - I'll try to expand a little on Dr Vikas' answer.
In my view, your medication needs a thorough review. If it is not working for you, there is something wrong with the regimen. You may also want to talk to your Doc about Trans Cranial Magnetic Stimulation, a recent, non invasive therapy which has shown success where traditional anti-depressants have failed.
OCD is personal - it manifests itself differently in each individual, and a well trained and capable therapist will tailor the CBT to suit you, and you alone. You see, CBT is not simply a series of steps ending in "Exposure and Response Prevention". That, frankly a great over simplification.
If the pattern of thinking we use, or our beliefs about our situation are even slightly distorted, the resulting emotions and actions that flow from them can be extremely negative and unhelpful. The object of CBT is to identify these ‘automatic thoughts’ then to re-adjust our thoughts and beliefs so that they are entirely realistic and correspond to the realities of our lives, and that therefore, the resulting emotions, feelings and actions we have will be more useful and helpful.
Cognitive therapists do not usually interpret or seek for unconscious motivations but bring cognitions and beliefs into the current focus of attention and through guided discovery encourage clients to gently re-evaluate their thinking. In other words, it's all about providing the clients with the tools and understanding to help them manage their own condition, and there is no 'one size fits all' approach
Therapy is not seen as something “done to” the client. CBT is not about trying to prove a client wrong and the therapist right, or getting into unhelpful debates. Through collaboration, questioning and re-evaluating their views, clients come to see for themselves that there are alternatives and that they can change.
Clients try things out in between therapy sessions, putting what has been learned into practice, learning how therapy translates into real life improvement.
Your therapist will take a fairly holistic view of your personal OCD, not treating it as a list of individual manifestations to be treated one after another. The goal of the whole process is to help you to re-structure your thinking, not to 'fix' things for you.
Also, there is a book called ”Feeling good - the new mood therapy” by Dr. David Burns. It has a hand book which gives you practical exercises to work through and further instructions on how to better use CBT. I really do recommend it.
Work with your therapist, but don't be afraid to disagree - that way you will win in the end.
