Just got laid off, what should I do first? after 11 years as a warehouse supervisor

I lost my job as a warehouse supervisor and I am not sure what to do first. 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. 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.
