I've always had triggers from angers, particularly from men. It could trigger past episodes where my father would lash-scream at me at times.
I've also had a problem letting go ever since I was a toddler. For instance, when a young kid stole a toy from me, I remembered it for 3 months and didn't want to meet up with him because of that.
Same with anger - it's never forgotten, but gets added up on and on until I've had it.
Now I'm back to talking to a friend whom I feel traumatized me and the memories and hurt feelings are not gone.
