Layoff happened 17 days ago, feeling lost (update)

I lost my job as a sales associate and I am not sure what to do first. I have a box of my things and a short letter about benefits. Which steps were urgent?

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

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