Just got laid off, what should I do first? after 14 years as a payroll clerk

They called a meeting on Monday and 14 of us were let go. I had been there 14 years. I am in San Diego, in case local advice matters. I have a few weeks of savings and a rent payment due. Which steps were urgent?

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