I am the same way and I see my therapy as a place to practice trying to be present, that being said, I'm not good at it. You probably just have an anxious attachment style, like me. Sometimes I even imagine I'm at the other end of a tunnel, lol, my safe place. In my worst sessions I can't cry or talk, instead I just freeze, and then I leave wishing I hadn't, always always. It's something you can wok on, but it can be a slow process sometimes... Actually I really am a lot better about it now
