"Raining In My Heart" is a song written by Felice Bryant and Boudleaux Bryant, but it became popularized by Buddy Holly, who recorded and released it in 1959. The lyrics describe a situation where everything seems perfect externally, with the sun shining, the sky blue, and no clouds in sight. However, the protagonist's internal state contrasts the pleasant weather as they feel a profound sense of sadness and longing. The song conveys the feeling of heartache and loneliness after a loved one has left. The protagonist mentions the Weather Man saying it's clear, but they know that their significant other has departed from their life. They express their misery and wonder what will become of them without the person they deeply care about. The lyrics also emphasize the struggle of hiding one's sadness and putting on a brave face to pretend that everything is okay. The protagonist tells their "blues" or sadness that they mustn't show, but they acknowledge that their tears will eventually flow because of the internal pain they are experiencing. Overall, "Raining In My Heart" captures the juxtaposition between external appearances and internal emotions. It serves as a lamentation of lost love and the longing for the person who has left. The rain serves as a metaphor for the protagonist's heartache and sadness, exemplifying the contrast between the pleasant external world and their shattered internal state.
