The song is exlpaining itself in the chourus. It talks about being alone because people easily look down on you for being different, having a different race, skin color, and etc. To better understand the song, imagine yourslef as a new student, because of this nobody respects you, nobody "sees" you, and nobody cares. It talks about the difficulty of finding a special someone who will be with you every step of the way, someone who respects you.
