Just got laid off, what should I do first? after 4 years as a hotel front-desk agent

They called a meeting on Tuesday and 4 of us were let go. I had been there 4 years. I worked as a hotel front-desk agent before this. I have a box of my things and a short letter about benefits.

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.
