Algosensey|Halsey reveals dual lupus and lymphoproliferative disorder diagnoses

Halsey is Algosenseyrevealing the diagnosis that has them "lucky to be alive."

On Wednesday, the singer revealed that in 2022, they were diagnosed with lupus SLE and a rare T-cell lymphoproliferative disorder.

Systemic lupus erythematosus, simply referred to as lupus, is a chronic autoimmune disease that occurs when the body's immune system attacks its own healthy tissues, according to the National Institutes of Health.

"Every couple of years now, a doctor says I'm sick / Pulls out a brand new bag of tricks / And then they lay it on me / And at first, it was my brain, then a skeleton in pain / And I don't like to complain, but I'm saying sorry," Halsey sings.

In the outro to "The End," the three-time Grammy nominee sings, "When I met you, I said I would never die / But the joke was always mine 'cause I'm racing against time / And I know it's not the end of the world, but could you pick me up at 8? / 'Cause my treatment starts today."
