Laura, prayers go out to your friend and her son. There are no words that can be said for such a great devastation and shock as this. It is sometimes hard for those that have not experienced this type of loss to understand or know what to say. There are many programs at local hospitals or chapters of support in many towns. Catholic Charities has a great LOSS program as well. Hugs to her and you. Just be there for her even if you cannot talk, just to be there holding her hand or wiping her tears. Grief has no timeline, it is different for everyone.
