Layoff happened 11 days ago, feeling lost after 11 years as a production planner

I was let go as a production planner this week and I am still in shock. It has been weighing on me all week. 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 got easier once I kept a simple log of every call and form.
