Laid off this week, where do I start? after 7 years as a delivery driver

They called a meeting on Monday and 7 of us were let go. I had been there 7 years. I worked as a delivery driver before this. I have a box of my things and a short letter about benefits. Which steps were urgent?

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