Layoff happened 6 days ago, feeling lost, warehouse supervisor here

I was let go as a warehouse supervisor this week and I am still in shock. Thank you in advance. I have a few weeks of savings and a rent payment due. Which steps were urgent?

File for unemployment right away. Do not wait for severance decisions. The date you file can matter.

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