Laid off this week, where do I start? (update)

They called a meeting on Thursday and 17 of us were let go. I had been there 17 years. It has been weighing on me all week. I have a few weeks of savings and a rent payment due. What did you do in the first week?

I made a short list: benefits, bills, documents, and then my résumé. One thing each day kept me steady.
