Who am I?

Who am I? Thats a deep question....
I am Amanda Lin in 9th grade. My school is PAS. I have a mom, dad, and sister. I like to play sports and sing and act.
This is what I usually say if someone want me to introduce myself, but the thing is, this is not me, at least not the whole me.
I may be a good kid to parents, good student who does her homework in school, but the truth is, I am crazy when I am with my friends. I am optimistic, well most of the time, I am always cheerful. Only my best best friends know that my heart is easily broken and that I am sometimes a very very sad person.
I am like a child, not only my size but how I think and how I act.
I am extremely sensitive. And think way too much.
I am always the psychologists for my friend, but can never treat my own illness.
I have three "brothers". They are not my real brothers, but to me, they are as important as real brothers. They are in this school, Jack, Godwin, and Robert Wang. They are the ones that always comfort me when I am sad. They are the ones that ask me many many times if I am okay because they know I am not. They are the ones who understand me and can always make me smile.
And one more person, that is sooooo important to my life, that I HAVE TO mention her. She is my best best friend- Candy. "I don't really know how to comfort people, but I can just sit by your side and talk to you, and if you don't want to talk, we can just sit there." This is what she told me before. She doesn't know how to comfort me when I cry, but she can always make me laugh. No matter what skills she have, I don't know and don't care. I just know that I need her and that I will never ever forget her no matter where I am.
I also have a dream...
That I don't usually tell people...
My dream is to stand on a stage and sing for competition. I love signing. And I love music.
This is me. The real me. The real me that only my best friends know about.
