Whoever your friend was she hit a nerve in you that is not often shown. I'm sorry this happened to you, but you might want to discuss it with your psychiatrist, too.

A friendship that provokes violence is one to question in your mind, I feel. Why would a friend want to create an atmosphere like that for you?

I'd think again about wanting that friendship; have you ever thought about trying to distance yourself from her a little to keep the calm? It might help.

I've heard it said that the closer we are to someone the greater the danger of
explosion.

Maybe she called you again because of the fear of losing the friendship. I'd have a
gentle talk with her, I think, if for no other reason than for your daughter's sake.

Take care of yourself.
