I don't think there is any reason to not set the appointment up at the end of session. Well other than I think she's doing one of those things where you have to ask for what you want. So I would have to ask to book it. I don't think I'm there yet. She was very clear at the beginning saying that she won't drag me in, that I can book an appointment whenever I feel I need one, whether it weekly, biweekly etc.

Maybe now that I've conquered the email, I can make another attempt at booking before I leave.
