After years of being misdiagnosed, pop star Halsey recently found out that she's living with endometriosis — an excruciatingly painful disorder in which the "tissue that normally lines the inside of your uterus...grows outside your uterus," according to Mayo Clinic.

Last Thursday, the "New Americana" singer opened up about her struggle with the disease, including the years she was gaslighted by healthcare professionals. Sigh.

"With doctors essentially telling me I was being a big baby on my period, or misdiagnosing PCOS," she wrote, "finding out that I had endo was the most bittersweet moment because it meant I wasn't crazy! I wasn't a 'baby!"

Endometriosis is incurable and can lead to myriad health problems, including infertility, so there's a lot of emotional pain associated with the disease. Still, Halsey stressed to her fans that they can live a baller life unencumbered by the stress of endo.

"I have managed to live a wild, incredible and unpredictable life with Endo, and I'm here for you,"  she wrote.

Sending you love, girl.
