文章中给的题目，帮我写一扁作文

How time flies! It has been two years since I came to XXX Middle school. In the two years, many things have happened. I also meet a lot of friends here.
Two years is not too long for man's life. But the two years I lived on campus has changed me a lot. For example, from the day I was born to the day I went to school, I had never left home alone for a long time and do housework by myself. How to deal with my roommates and classmates? These questions were all difficult for me to work out at that time. Today I get on well with them and do everything in life calmly. But all these changes were not easy for me. Sometimes I feel lonely, angry and also homesick. But fortunately I meet a lot of good friends. They helped me spend these sad days. I find words cannot express my sincere thanks to them. When they need help, I will do everything I can to help those who helped me before.
