Wow, sounds like this has had quite some impact on you! first of all, in case she hasn't realized, I think it would be kind of you (though of course you don't have to) to let her know her mistake. I also think that, if these questions are important to you, it might be very useful to discuss them. It could be significant in your therapy and besides it's the kind of thing that may have impact on your therapeutic relationship, so also depending on your therapist's openness and school of thought, I'd tell her. On the other hand, please be aware that most of these (other than asking if she'll be away in December) are actually quite personal and you may or may not get an answer to them. But I think it would be worthwhile to try and even just discuss your need to ask.
