Why Am I Me?

sometimes I can't help but wonder why I am the way I am. why am I depressed? why am I a loner? why do I get depressed when I'm with my friends? why are my friends my friends? everyone is so much better than me at everything, why am I here? I have no talents. I used to think that I was an artistic person because I liked to sing. now I realize that I'm not artistic at all, I can only sing other people's words and never my own. why do I have these dreams of the same person every night? someone I hardly know. why am I me?
