Laid off this week, where do I start? - 2 weeks in

I was let go as an event coordinator this week and I am still in shock. There are 18 people counting on me, so I am trying to be careful. I have a box of my things and a short letter about benefits. What did you do in the first week?

Give yourself the first couple of days to be upset. I did, and then I felt able to plan.
