Just got laid off, what should I do first? after 4 years as an HR coordinator

I was let go as an HR coordinator 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 few weeks of savings and a rent payment due. 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.
