How much time did you take off work when your mother (or loved one) passed away?

My mother passed away a little over a week ago and so I took a week off from work to spend time with the family and tend to funeral arrangements. I just came back to work this week however I am still feeling a little tired from the whole ordeal. How much time did you take off from work to grieve your loss? I was told going back to work for some people helps them during the grieving process in that it keeps their minds and bodies busy.
