Laid off this week, where do I start? (update)

I was let go as a copywriter 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?

Keep everything in writing and save the confirmation numbers. It saved me later.

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