Just got laid off, what should I do first?

I was let go as a graphic designer 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 7 months ago, and it settled down 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.
