Billie Eilish Pirate Baird O'Connell (/ˈaɪlɪʃ/ EYE-lish; born December 18, 2001) is an American singer and songwriter. She first gained attention in 2015 with her debut song "Ocean Eyes", which was subsequently released by the Interscope subsidiary Darkroom. The song was written and produced by her brother Finneas O'Connell, with whom she collaborates on music and live shows. Her debut EP, Don't Smile at Me (2017), became a hit, reaching the top 15 in the US, UK, Canada, and Australia.
But as all people, she also is prone to fall victim of fears and in worse cases phobias. In a quite introspective interview for Billboard she confesses that as for what her biggest fear is, Eilish confesses that she is terrified of people she loves dying. “That's like, all I think about all the time,” she says. “I think that's probably my biggest fear is losing the people around me. I'm not afraid of death, but I'm afraid of people I love dying.”.
She adds that she is afraid of the ocean, as well, noting that whales and the sounds they make are “fucking creepy as hell.”
There are a lot of phobias associated with large bodies of water but the most popular one is thalassophobia which is fear of sea, sea travel, large bodies of water, emptiness of sea and in Billies case - Falainaphobia, which is fear of whales specifically.
