When I've been in similar moods, I still go. No, it does not usually lead to a great, connected session, but it does give her a chance to see how I'm doing, what the anxiety is like for me, etc. I mean, that is part of what I'm seeing her for, so she should get to see it in action. Also, I know me, and I think I would regret it afterwards (feel like she wasn't there for me, even though I'm the one that cancelled, etc.).

But if you're already past that point in your relationship, and feel it would just be a waste of time/money, I could see just choosing to take a week off. Good luck. I hope you can find a peaceful place to rest up
