Just got laid off, what should I do first? after 16 years as a janitorial supervisor

I lost my job as a janitorial supervisor and I am not sure what to do first. There are 16 people counting on me, so I am trying to be careful. I have a few weeks of savings and a rent payment due. Which steps were urgent?

Ask for your final pay, unused leave and any documents in writing before you leave, if you still can.

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