Laid off this week, where do I start? after 9 years as an accounts payable clerk

I was let go as an accounts payable clerk this week and I am still in shock. I have read a lot of threads here and could not find my exact situation. I have a box of my things and a short letter about benefits. What did you do in the first week?

Give yourself the first couple of days to be upset. I did, and then I felt able to plan.

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