Just got laid off, what should I do first? (update)

I was let go as a store manager this week and I am still in shock. I am in Knoxville, in case local advice matters. I have not told my family yet. Which steps were urgent?

Keep everything in writing and save the confirmation numbers. It saved me later.

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