From my experience, it means you need a break or a vacation. Get in a totally different environment for a few weeks days and do not bring anything related to work.
If it is not possible at this time, you may buy time using a trick I have used in the past. Dedicate a part of your day to working (ex: afternoon) and dedicate another part of the days to something else entirely and in a different environment (spend the morning playing sport, walking, exploring the neighborhood, anything out of your work environment and off the computer).
