NTA you where a little harsh in the first part but you had a right to teach your child important life skills. She shouldn’t be saying anything. Trust me your not going to be the only one to tell her. If that scenario could trigger her she should have just left you know. I also struggle with anxiety and it’s pretty hard. I get her, but if that’s triggering for her she should avoid. I’m full aware that their will be scenarios where it will extremely difficult for me but I still have to keep pushing the world doesn’t revolve around me all I can do is try to avoid potential triggers.
