You're in class; your teacher is having the whole class write an essay on what you want to do in the future. You look around, seeing everyone writing. You look at the blank sheet of paper in front of you; your hand shakes and grips your pencil tightly. Your lip quivers, and your blood boils as you wonder why you feel this way. You accidentally snap your pencil, slam your hand against the desk, and walk out of the classroom.
