I translated my opinion into English as you can see below. Please correct it if there are some wrong or unnatural expressions.

I believe that students should be required to study music in high school for the following reason.

Music knowledge can make my life better. For example, when I was a first year student in high school, I could not make friends with anyone. Since I was very lonely, I cried every day. In order to relieve the loneliness, I drunk myself dead drunk everyday. My friend was only alcohol. However, one day, I was asked to listen to Mozart music in my music class. When I listened to the music, my distress appeared and I took a fancy to his music. I started to enjoy the music instead of drinking. What is more is that I could make friends with a classmate who also likes Mozart. We enjoyed talking about his music and promoted our friendship. My life could be much better. Thanks to my music knowledge, I cloud make friends and improve my life
