I am looking at things I am doing that I can step back from that are not job related. I get involved in too many things routinely. If working from home is an option it sounds feasible- you can take mini breaks as needed and get the job done. I am trying not to think about work yet as it stresses me out. The walking, the standing, and wondering how I can get my necessary student materials together. This is hands on things not worksheets. Trying to trust that OS will properly advise. It’s not a moan by no means.
