Emotion Sickness is a song by the Australian alternative rock band Silverchair. It was released as the first song on their 1999 album Neon Ballroom. At 6 minutes long, it is the band’s third longest song. Although the song is not typical of Silverchair’s work, “Emotion Sickness” is a fan favorite. The band’s frontman, Daniel Johns, said about the song: “It’s about fighting against the need to get some kind of medication and trying to pretend that you’ve got a normal state of mind when you know for a fact that you haven’t.”David Helfgott makes a guest appearance on the song.
