Scared about getting covid and feeling resentful

I was called back to work in the office full-time from Monday through Friday last week. It’s a far commute and also there’s a risk I might get Covid and put my family in danger. I was laid off so I was happy to be back early and accepted it. The first week of going back is very draining and I feel tired and scared.

Most of the other fun people of the office are still not coming back until mid-November. I just feel unsafe and used. I need advice. I feel powerless.
