Just got laid off, what should I do first? (update)

I lost my job as a production planner and I am not sure what to do first. Any experience at all would help. I have not told my family yet. 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.
