"Stin Kardia Mou Mono Thlipsi" (Greek: Στην Καρδιά Μου Μόνο Θλίψη; English: In my heart there is only sorrow) is a song recorded by Greek-Swedish recording artist Elena Paparizou and written and produced by Grigoris Petrakos. It was released as the fifth and final single from the original edition of her debut album, Protereotita (2004). The song is a downtempo laïko ballad which lyrically speaks of sadness after a break-up and wishing the person to return. It was released in early 2005 shortly after the Hellenic Broadcasting Corporation's (ERT) announcement of Paparizou as Greece's entrant in the Eurovision Song Contest 2005. The song was not heavily promoted and a proper video was not filmed; rather the video was made at the set of a television interview special she had done in Stockholm.
