Hugs if wanted, Velcro. I completely understand your anxiety about this, and I'd be freaking out, too (that doesn't mean this is what she was thinking or is going to say--just that I'd also be anxious).

If it were me, I'd have sent her an email earlier this week (or today) saying how I'm really anxious about the email I sent. If she's already bothered by the emails, one more wouldn't really affect that, I wouldn't think. If it's a case where she just didn't have a chance to respond before and isn't bothered by your emails, then maybe she could either let you know that by email before session or say something right at the start of session.

But I also understand your not wanting to do that. I'd bring it up right at the start of session so that you're not anxious the whole time. If you don't think you can say it, maybe write or type on a piece of paper you can hand to her at the start of session? I really hope it turns out to be nothing.
