Just because they ask, that doesn't mean you have to answer. Just speak up and tell your T that you don't want to answer. I have this belief that therapy is really just mostly being able to bring up your thoughts and feelings about what is happening in that room. Even when I am doing trauma work with my T, it is still a lot of what I am feeling in the moment and how that links back to the past. The more transparent you can be, the easier it is to get to the heart of the matter/matters.
