Halsey shares details about the rare health checkup as news was announced this week that she was diagnosed with both systemic lupus erythematosus and T-cell lymphoproliferative disorders, Entertainment Weekly reports.

The singer — who uses her/their pronouns — wrote in an Instagram post yesterday that the diagnosis will be down to 2022 and both are "currently in control or in remission."According to an instagram post, they wrote: "And both will likely have me for the duration of my life.

According to the Lupus Foundation of the United States, systemic lupus erythematosus is the most common form of lupus, an autoimmune condition that can cause swelling, fatigue, and inflammation of internal organs and systems. T-cell lymphoproliferative disorders often occur in immunodeficient individuals and are often present as leukemia or lymphoma.

Halsey's post yesterday followed a more ambiguous post on Tuesday, with Entertainment Weekly promoting the song "The End," "Referring to doctors, diseases, poisons, treatments, and death." "I told myself I'm giving myself another 2 years to get sick," Halsey said in the video. At 30 years old, I have a rebirth, and I'm not going to get sick, and I'm going to look super hot and have a lot of energy and I'm just going to get to redo my twenties in my thirties.

They suggested that the positive response to "end" was inspired by instagrammers, which provide fans with additional context: "I think everyone wants to share a little more because I've been saying "You guys have been so kind" for a very long instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrammed instagrams."

They thanked the medical personnel for helping along the way, and continued: "After a rocky start, I slowly controlled everything with the help of an amazing doctor 2 years later, I feel better and more grateful than ever that I was able to turn to music. I can't wait to return to where I belong: with all of you. Singing and screaming my heart.

Halsey will donate proceeds from "The End" to the Leukemia & Lymphoma Society, as well as the Lupus Research Alliance. "If I make a long story short, I'm lucky to be alive," they write.
