Jack sounds lovely. I had a huge, soft black cat named Carlos when I was a preschooler. He was the most loving guy. He taught my sister how to crawl.

I don't know about ERs but I know that there's at least one urgent care here that you can go to for a test. You call from your car and I think they bring the test to you (not sure about that, just guessing from the sign saying you are to call before entering if you are there for a test). You may be able to get a free test from a pharamcy; I know I've done that but it was a while ago and I don't remember the details. If you call one they can tell you details. CVS here has a whole extension for COVID related issues.

I hope you start feeling better soon. Feeling terrible for so long is awful.
