Not just a school or work task that deals with deadlines, but sadly also have to have deadlines. You can cry sadly, listen to the song as much as possible or write the diary with the most dramatic expression though, but remember after that all passed we have real life that we must pass.
Sad continuously for a long period of time will have a bad impact on our lives. Here we need to give a deadline, how long do you have to be sad? A week? A month? A year? How long?
