Just got laid off, what should I do first? after 16 years as a data-entry clerk

They called a meeting on Wednesday and 16 of us were let go. I had been there 16 years. It has been weighing on me all week. I have a few weeks of savings and a rent payment due. Is there a checklist I should follow?

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