Maybe all of you already know about the word “smile”. Show the uses of smile

Maybe all of you already know about the word “smile”. We always smile when we are happy; that means you’re expressing your feelings and moods. And of course when you smile, that is the happiest day of your life. But today, I'm gonna show you another use of a smile. Smiling helps us to hide our true feelings. For example: your friend smiles. But actually, she isn’t happy; she smiles because she wants to hide her true feelings. If you don’t understand, I will take myself as an example. I am a normal person in my family, my school and my friends. I study well and am also the main member of the English team in the class. Besides studying at school, I also went to an English class that a teacher taught in the city to study higher. Everyone in the place I’m living always calls me "one's treasure" because I study English very well and my family is very proud of it. My friends told me that a person like me doesn't have to study a lot. But they are wrong… Students like me have to study higher and have to have higher marks than a normal student. For example: Instead of getting 9, 75/10, I have to get 10/10. That is really hard because I sometimes make some mistakes. Because there were also some mistakes in the review, from the teacher to my parents, everyone yelled at me and asked why it was wrong every time? When I said the review was a bit difficult, they said that I didn't pay attention to study. No matter how I explain it, they don't care, even think I'm arguing. I was really sad about it. Not long after that I got to know a friend through facebook through role-play in a fandom group. He is really nice and he also said that he was once in the same situation as me. We talked to each other really friendly and we became best friends. My mother knew this and she thinks this is the reason why I do not study well so she blocked him secretly. I knew it not long after that and was very shocked. I was really sad and cried all the nights when everyone was asleep. When I ask a teammate in that fandom group, I know that she has the phone number of the friend that my mother blocked so I asked her to give me the phone number. We met again. He asked me why I blocked him and I told him the truth. He believed me and we connected to each other again after 2 weeks. But now I am facing pressure from studying at school. I was really tired and exhausted. I only sleep 1-2 hours/day because of nightmares. Once I was think about buy sleeping pills for suicide. If my friend didn’t comfort me, I'd never sit in front of the computer to write this task. My family never knew this. If they do, they will tell me that I’m neurotic. So I keep this as a secret… My friends in my school sometimes asked me if I was okay, I lied to them that I’m fine. If they don’t believe me, I’ll pretend to SMILE… Yeah. That’s right. Pretending to smile. It helps me hide my true feelings.
