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

They called a meeting on Monday and 10 of us were let go. I had been there 10 years. Thank you in advance. I have not told my family yet. Which steps were urgent?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.

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