Just got laid off, what should I do first? after 14 years as a paralegal

They called a meeting on Tuesday and 14 of us were let go. I had been there 14 years. I am in Providence, in case local advice matters. 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 got easier once I kept a simple log of every call and form.
