Reader call: What to do for friend during tragedy

Nicole writes:

"In what can only be considered the most tragic situation ever, a friend of mine delivered and lost her son on Christmas this year.  I am truly at a loss for what to say or do, although we have emailed a few times (she is not ready to talk to people yet, understandably).  I have offered to bring food, go hang out with her, do anything she needs.  My heart is just broken for her, and I want to help.  Suggestions on what friends can do to support each other during a time like this?"

I'm also at a loss. Can anyone who's been in a similar situation, or who's helped a friend through a similar situation, please help?
