Just got laid off, what should I do first? - 3 weeks in

I lost my job as a customer-service rep and I am not sure what to do first. I worked as a customer-service rep before this. I have not told my family yet. Is there a checklist I should follow?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.

I made a short list: benefits, bills, documents, and then my résumé. One thing each day kept me steady.
