Glad you're doing better. I know anticipatory fear well. Try to approach it as just a time to listen. Even if she drops a bomb on you, you keep DBing by not reacting, listening, and validating. Maybe just what your R needs. In other words, it is under stress and test that we show our stuff. W takes note, even if it is subconsciously: this is not the same old PP. What's going on here? So, you never know whether it is a good or bad session until long after, and maybe never.
Do you know the parable of old Chinese farmer? Farmer's horse runs away, and his neighbors tell him "oh, what bad luck." All he says is "maybe." The next morning the horse returns with 3 wild horses in toe. The neighbors say, "oh, what good luck," and the farmer replies "maybe."
His son falls from one of the wild horses when he tries to break & tame it, breaking his leg badly. The neighbors say, "oh, what bad luck," and the old farmer replies "maybe." The next day, the military visits the village to conscript young men to serve. They reject the old farmers son because of his broken leg. The neighbors all say, "oh, what good fortune," and the old farmer just says "maybe."
As you feel the fear of your session coming up, just sit with and explore that fear. Befriend it. Find out what it really is a fear of/where is it coming from? What does it tell you about your core belief in how the world should work. That is one of the best ways I've found to take some of the power out of anticipatory fear, and I'm a pro at getting myself twisted in knots about the future.
Good luck.
