I’m so sorry this has happened. It sounds like she forgot that she asked to change the appointment time to 5? Not that it’s an excuse or anything.

I’d feel like you are feeling too. It’s horrible. They are supposed to make you feel like you matter (because you do) and they are supposed to be a constant presence. Changing times and then forgetting about it doesn’t exactly make one feel safe and heard.

Have you maybe thought about emailing her all of this? She should realise how triggering this can be, but maybe if you send something, she’ll realise and remember for next time?

Again, sorry you’re dealing with this, I think I would lose it if it happened to me.
