Layoff happened 3 days ago, feeling lost - first time posting

I was let go as a pharmacy technician this week and I am still in shock. I worked as a pharmacy technician before this. I have a box of my things and a short letter about benefits. Which steps were urgent?

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

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.
