Singer Lady Gaga has revealed she suffers from post-traumatic stress disorder after she was raped at the age of 19.

The incident had occurred when she was in Catholic School, with her rapist 20 years older than her at the time.

She revealed this while visiting the Ali Forney Center for LGBT homeless youth with  The Today Show‘s Hoda Kotb. “I told the kids today that I suffer from a mental illness,” she said on the show about her visit.

“I suffer from a mental illness – I suffer from PTSD. I’ve never told anyone that before,” the 30-year old singer said.

Gaga pushes for a kinder world through her Born This Way foundation, and she brought gifts for the teenagers at the center. She revealed that it was the same kindness that saved her. “The kindness that’s been shown to me, by doctors as well as my family and my friends, it’s really saved my life.”

“I have a mental illness, and I struggle with that mental illness every day,” she stated, adding that she used meditation to keep it in check.

She has a song titled Swine on her previous album Artpop, and had revealed in the past that the song was about the rape incident. “The song is about demoralisation. The song is about rage and fury and passion, and I had a lot of pain that I wanted to release.”

“These children are not just homeless or in need; many of them are trauma survivors, they’ve been rejected in some type of way,” she told The Today Show. “My own trauma in my life has helped me to understand the trauma of others.”

“It’s really important to remind kids who are suffering from a traumatic experience or from abandonment, to remind them that they’re not alone, and that they’re loved,” she continued. “We are in this together.”
