Stress at Work After Death in Family

My boyfriend is dealing with a stressful situation right now at work with a colleague who is angry at him ... without going into details, pretty much unjustifiably so, and this particular colleague just lost a close family member.

I remember when my grandfather died, it was a MASSIVELY stressful time for my whole family. And that stress carried over to me personally. And I'm sure that stress carried over to work. I remember even telling a few people that I was extra cranky because of a death in the family and that I was working to de-stress and be less cranky. And as I found myself getting angry at work, I'd try to take a step back, think about whether there was really something happening at work that justified anger—and probably there wasn't.

But man, it's so hard to deal with logistical details of funerals, visitations, financial settlements, travel arrangements, etc., on top of all of the emotions of grief. And then you have to get back to work. Argh! That's a tough transition. Have other people had experience with this?
