Just got laid off, what should I do first? after 3 years as an electrician's helper

They called a meeting on Monday and 3 of us were let go. I had been there 3 years. I have been trying to stay organised about it. I have a box of my things and a short letter about benefits. What did you do in the first week?

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