Just got laid off, what should I do first? - 4 weeks in

They called a meeting on Friday and 16 of us were let go. I had been there 16 years. This is my first time dealing with any of this. 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.
