My T has specifically told me that I *should* interrupt him if he's going off on a tangent or seems to be totally misinterpreting what I'm saying/feeling. Anytime I start to interrupt him, I stop and apologize out of habit, and he nearly always just says, "It's OK, go ahead." Sometimes I do, other times I tell him to finish what he was saying first. But he's never seemed annoyed about it at all.

If you say she's not usually like this, I imagine it's the stress of the move, of having last sessions with lots of clients, and she's probably distracted. I'm not saying it excuses how she acted toward you, just that I suspect it's not about you in particular. As for saying she'll see you Friday, I can't think of how many times when we're parting ways, my T has been like, "It's Monday, right?" then when I confirm, he says, "OK, see you Thursday" (I see him twice a week). Or he'll say, "It's Thursday, right?" and if I say yes, he'll say, "OK, have a good weekend then." I often forget what day it is, too! And if you normally see her Fridays, she likely just said it out of habit. If you're concerned she doesn't have you on the schedule for Tuesday, you could call or e-mail to be sure.
