| I can still remember the first day when I met my best friend. I hid behind my mother and she hid behind her grandmother, 1 to look at each other. But we soon lost the 2 and started playing with each other. In the 7th grade, I first lost touch with her. She was 3 family problems and I deserted her to be with the "cooler people." 4 of my new friends liked her as much as I did 5 they knew she had "problems". However, every summer we would 6 sit at each other's home and watch soap operas and talk about everything we liked. It was last year when I 7 the problem. I guess I was just too busy in high school to realize she needed someone there for her. Well, she made a new "best friend" and 8 did I. Then I didn't know why, but she started cutting herself. She was diagnosed with clinical depression(抑郁症). I was very 9 at first, but with the late night calls, we still stayed in 10 . I wanted to be there for her since her new best friend 11 deserted her, when people were calling her 12 , but I knew I still 13 her like a sister. Yesterday she came 14 me and said this," I never knew what a best friend was 15 I found you were the only person that would stop me from cutting, the only person that ever made me feel better about myself and my 16 . You don't know this but I was trying to kill myself one night when you 17 me. I 18 you so much, and you didn't even know you were 19 me." We both cried. And I guess a kind of lesson from my life so far is to never 20 your friends. | ||||
