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

They called a meeting on Thursday and 13 of us were let go. I had been there 13 years. I have not told my family yet. Which steps were urgent?

Thanks for writing this out. I went through something close to it 4 months ago, and it settled down once I kept a simple log of every call and form.

File for unemployment right away. Do not wait for severance decisions. The date you file can matter.
