Sorry to hear about this Neph.
I can kind of understand what shes going through, I lost a grandfather figure recently. I never had any grandfathers because they all died before i was born except for one who lived in a different city(who died when i was 10). The guy who was like a grandfather to me died in October(Canadian thanksgiving weekend actually). I cried...I never cry...until that point, I hadn't cried in almost 5 years. Like people have said a few times in this thread, losing a loved one is hard but is easier when someone is there for you. Just be there for her. Don't try to make things better, that'll only make it worse, just go with her through the griving process.
