I totally get it, and I think she may have picked up on your anxiety and thought it was something else. I have actually had that happen in work meetings with people when I'm having anxiety, often unrelated to them, and they think I'm mad at them or something they did, when usually it has nothing to do with them. I've learned to just be really honest and let them know I'm trying to get something else out of my head, and they get it, but what I'm saying is that others can pick up on our anxiety, but they don't realize it's not really something about them, rather it's just something going on with us. It might be that she misinterpreted your anxiety.

Regardless, the whole thing sounds like a misunderstanding. Try not to beat yourself up about it. I recently had to apologize to some business partners because they misinterpreted me being upset about something as being upset at them about something, when it was nothing of the sort. It's just miscommunication. We continue to work on ourselves and improve and learn lessons.
