I was away on the weekend I did not hear about it.
Sorry to hear about it. Give your daughter a big hug from us and give her the time and space to talk about it and about her friends.
It takes time, and it will hit in unusual and unexpected ways.
Getting over it is like a scar healing when it is new every time you bump it it hurts slowly it becomes less tender untill it is just a memory, but you will still have a scar and that will remain for the rest of your life.
