Can you ask your therapist to break down your work into smaller more manageable bites? When I read your first post I felt overwhelmed at the thought of trying to apply new skills to every feeling and situation after only 4 sessions. (Maybe that's not what your T intended but that's what I took away from your post.)
It sounds like you're aching to be listened to. I'm not sure how you can get that patient non-judgemental listening while simultaneously being coached to retrain your thoughts and actions. (Because you're being judged on how well you're applying your new CBT skills.)
I'm not the hugest fan of CBT for myself but I appreciate miswimmy's perspective about it and definitely see a role for it in targeting certain symptoms. I'm not sure you can have it both ways though. At least not in 20 sessions.
What is your priority? Can you try out your CBT skills to manage one type of compulsion that you choose to target? Can you set aside a part of each session just to be heard and have your T promise not to jump in and tell you how to CBT your feelings away? Maybe?
