Layoff happened 13 days ago, feeling lost - 26 weeks in

They called a meeting on Wednesday and 13 of us were let go. I had been there 13 years. This is my first time dealing with any of this. I have a box of my things and a short letter about benefits. Is there a checklist I should follow?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

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