The first two verses represent the way Eminem was thinking when he was a kid. These two verses contrast to the third verse, where Em saying that he is proud of who he is, and that he is happy that he is not like anyone else.
The song is a message to every person of the same age that Em had when he was being bullied, saying that it is a good thing to be different. Do not let anyone tell you you’re wrong. The message of this song resembles Beautiful:
Even if it sounds corny
Never let no one tell you you ain’t beautiful
