Laid off this week, where do I start?

I was let go as an electrician's helper this week and I am still in shock. I have a box of my things and a short letter about benefits. Which steps were urgent?

Thanks for writing this out. I went through something close to it last year, 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.
