I like what hvert said. Unless staying in bed or on a couch causes you to neglect your pets or children or some other incapacitated human beings, there really is no “should”. I grew up in a family where being 24/7 busy is an expectation. I perpetually feel guilty if I don’t do something all hours of the day. But if for how many days you need to be in pajamas on a couch, well maybe give yourself a break. It will get back to normal as it always does.
