I understand why you don't want to have the session before your 2 week break. I think if I hadn't had the session when I came back from being away for 2 weeks, right before my T's vacation, I may not have been in such anguish. On the other hand, I probably would have been anyway. It's hard to predict, so I think seeing T is always better. In your case, I would not want to sit with my feelings for 2 more weeks.

I wonder if your T is going to feel comfortable making the decision for you. Maybe she wants YOU to make it, which of course is infinitely more difficult, isn't it?

Oh, I realize YOU want to cancel, not a difficult decision, but will go if she tells you to. Sorry.
