Laid off this week, where do I start? - 13 months and counting

I was let go as a bank teller this week and I am still in shock. I worked as a bank teller before this. I have a box of my things and a short letter about benefits. What did you do in the first week?

Thanks for writing this out. I went through something close to it 13 months ago, and it got easier once I kept a simple log of every call and form.
