The flu is a jerk with a stopwatch. It lasts longer than a cold (three days) but shorter than it feels (eternity). The current strain is particularly clingy, but it’s not invincible. You will emerge, blinking, into the sunlight, wondering where the last week went.
So stock up on tissues, cancel your plans, and remember: this too shall pass—preferably through a nose. And if anyone asks how long it lasts, just tell them: “Five to seven days of misery, plus two weeks of bad allergies for the road.” Then go take a nap. You earned it.
