Lady Gaga has been vocal and transparent about being sexually assaulted at 19 by a music producer and now—in a new interview with VogueGaga went into painful detail about the lasting imprint that teenage trauma left on her life, and how she believes that her rape triggered her current struggle with fibromyalgia.

When asked to describe what her PTSD symptoms feel like now, Gaga says it’s like she’s on a “roller coaster.”

Despite her transparency with her assault, Gaga admitted that she’s “still in disbelief,” adding, “I think every person has their own relationship with that kind of trauma.”

Last year Gaga admitted that she struggles with extreme nerve pain caused by fibromyalgia and released the Netflix documentary Gaga: Five Foot Two to shed light on the often misunderstood illness. Gaga also believes that her current chronic pain and her sexual trauma are connected. A 2005 study in the Clinical Journey of Pain showed that women with fibromyalgia were 3.1 times more likely to have been raped and more likely to have a PTSD diagnosis than women without fibromyalgia.

As always, we stand with Lady Gaga and other sexual assault survivors who speak out about their experiences. Head over to Vogue for the full interview.
