Start by setting realistic expectations. A normal human can only do about 4 hours of difficult work per day before burning out. The whole office thing was/is a way take 4 hours of work and make it feel like an actual workday. If you don't have stupid/annoying tasks to do outside of those 4 hours that's a good thing - don't miss it or feel inadequate.

Next try to move around or set non-work tasks or outdoor tasks for breaks or even during all-company calls if you have them. Going for a walk or gardening or even laying outside in the sun for a 60 minute zoom call that you're only a passive observer on does wonders compared to sitting in an all-room office.

Also avoid any escaping behaviors (e.g. addictive) like alcohol, drugs, video games, social media, etc. If you start doing these things from a place of weakness things get ugly fast. Only do them from a position of strength like celebrating something not because you're bored/unmotivated.
