Your mental health is more important than any kind of school project. Put down that pen and go to sleep. You deserve it. Sometimes you need at break from school, work, or people. Everyone needs breaks sometimes and if the teacher, boss or anyone else doesn’t understand why your report isn’t done, you skipped a day at work, or you didn’t want to see anyone for the day, then just tell them. Tell them that you needed a well deserved break. You are far more important than anything else and you come first. If you don’t want to do something, put it aside for later. Do something you would like every once in awhile.
