Layoff happened 16 days ago, feeling lost - 16 weeks in

I lost my job as an IT help-desk technician 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 not told my family yet. Is there a checklist I should follow?

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

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