What is the story behind Helena by your chemical romance?

The song "Helena" by My Chemical Romance is a tribute to Gerard Way's grandmother, Elena Rush, who passed away from cancer when he was a teenager. The song expresses his grief and longing for her, as well as his struggle to come to terms with her death. The lyrics are filled with imagery of loss and despair, such as "The world is ugly, but you're beautiful to me" and "I'm just a notch in your bedpost, but you're just a line in a song." The song also features a spoken word outro in which Way recites a poem he wrote about his grandmother.

"Helena" was released as the second single from My Chemical Romance's debut album, "I Brought You My Bullets, You Brought Me Your Love," in 2002. The song was a commercial success, reaching number 33 on the Billboard Modern Rock Tracks chart. It has also become one of the band's most popular songs, and is often played live at their concerts.

The music video for "Helena" was directed by Marc Webb, who also directed the music videos for "I'm Not Okay (I Promise)" and "The Ghost of You." The video features the band performing the song in a cemetery, and includes scenes of Way and his grandmother. The video also features a cameo by actress Alexis Bledel, who plays Way's love interest.

"Helena" has been praised for its emotional intensity and powerful lyrics. It has been described as a "heartbreaking ballad" and "a song that will stay with you long after you've listened to it." The song has also been credited with helping My Chemical Romance to gain a wider audience, and is considered one of the band's most important songs.
