Help I am having an identity crisis!?

I really like this girl from my dance she is tall and a gorgeous dancer, perfect turnout, perfect arabesques, she was in Young Canadians and can sing, she is 14, that is how old I am, home schooled with a 96 average, her parents are nice she has a dog and is wealthy but without showing it off, all the teachers like her at my studio, and she gets all the solos, she has long stunning hair that is naturally wavy, and she cut it at the beginning of the year for cancer to her shoulders and now it is half way down her back and she is cutting it for cancer tomorrow, but i feel bad becuase my best friends mom has breast cancer and I feel like I should do someh=thing like that but I have shorter hair.. She has perfect complexion big boobs, and perfect teeth!! SHE NICE!! and i dont know what to do because I am like oh I want to be like her, but I want to be me, but I want to do what she is doing like cutting her hair for cancer, but I also kind of have a hair fetish.. so i dont know!! HHHEEELLLPP!!
