Fawn/freeze/flight mode and shut down after being yelled at

Was in a situation where I got full shouted at on the weekend. I froze up/fawned and then as soon as I could, ran and cried in the bathroom until I can semi pull myself back together, very embarrassed.

The person later apologised, and people keep saying "that's just how they are", or "they're like that with everyone".

This person apologised for making me upset, and said/made the observation to me that they yell at everyone over these things, so it's not just me - not a personal thing etc.

And while I understand the reason I was pulled up and addressed, I feel that the way this person went about it was so incredibly out of order and that it's unacceptable for a person in the position this person is in to speak to people in that way.

It was four days ago, and I have wanted to self harm more in the last four days than I have for ages.

I am aware that I've been in a heightened emotional state over the last little while, so I am also factoring that in.

I also have borderline personality disorder, and possible other neurodivergent stuff is always there,

But I really feel so so raw and emotionally out of whack, and cross that I was put in that situation.
