I may be wrong, but I feel that I decide what kind of session it's going to be. I just don't feel pressured in any particular way to have a hard or light session. At the same time, it never feels like a waste or that my therapist is dialing it in. Then again, I sometimes really like lighter sessions. Maybe they help re-balance things. I'm not sure. I do know that the longer I see her, the more comfortable I am with whatever happens or doesn't happen.
