B..
In a physicians office, a dental office, yes. I think in a therapists office, I can see why they wouldn't. I mean, you are there to help yourself. (Which is so awesome, by the way!!) Is it really helping you, if they take responsibility for your appointments? If you had issues where they though you were a danger to yourself or someone else...of course, that would be different, I think they'd like you to manage your time and appointments...as part of the accountability.
It's just my opinion, and I very well might be in the minority. The important part, is this is probably not a personal jab at you from the therapist. She could have felt you weren't invested, or weren't ready. Therapists have to walk a fine line of being firm, and giving you control. She is probably just trying to appropriately walk that line.
