Thanks everyone..
My personal trigger is a phrase my ex husband always said to me. I've gotten to the point where hearing most people say it or reading it or whatever and all I need is a deep breath and I'm fine. I've worked hard to get to this point. Hearing my daughter say it to me while I was making sure she handed in homework (she's still virtual for school and has a history of turning assignments in late)... it just hurt. I went through my groundings, didn't cry, focused on the task at hand... I got through it like one gets through a funeral if that makes sense.
Maybe I'll call my doc tomorrow. I feel like waiting a week is going to be worse than asking my daughter not to use the saying.
