Laid off this week, where do I start? after 9 years as a copywriter

They called a meeting on Wednesday and 9 of us were let go. I had been there 9 years. This is my first time dealing with any of this. I have a box of my things and a short letter about benefits. What did you do in the first week?

Ask for your final pay, unused leave and any documents in writing before you leave, if you still can.
