Super Star in Taiwan died for....?

There is a girl called Tru Ning Li in Taiwan, she went audition for the Super Star...., which is a show that's for people in Taiwan and other countries to come and show your talent, base on singing, and to compete. She is a very talented and a great singer, she was the 5th or the 4th(i am not sure)of the Super Star...show. There is an unfortunately thing happened, she died. I think you would be very curious about why? She wrote a letter before she suicide, she wrote about how her boyfriend hurt her or something, her father doesn't really want to talk more about it in front of the crowd. She is such a talented and happy good girl, why does she need to kill herself just because a man hurt her. I can't decide or say she's not right, but my thought is that living in the world it's always the best thing and wonderful thing in the entire world. I hope everyone including me could live very good, healthy, and happy.... :D
