Layoff happened 7 days ago, feeling lost

I lost my job as an office manager and I am not sure what to do first. I am in Tucson, in case local advice matters. I have a few weeks of savings and a rent payment due. Which steps were urgent?

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

Ask for your final pay, unused leave and any documents in writing before you leave, if you still can.
