Ohh hun im so sorry for your Friends loss xox
How heartbreaking for her and her family.

i havent got any great advise as ive never been through something like this before, but just being their for her will mean alot to her im sure, sometimes times like this people worry so much (as they do) and get so scared of upsetting the person in some way that they miss actually being there for the person because of that fear, i know its easily said than done but try and focus on being their for her and asking and offering as much support as possible.

You sound like sucha great friend hun, your friend is verry lucky to have you beautiful xx
