Actor Amber Heard, who in 2016 accused ex-husband Johnny Depp of domestic violence abuse, revealed the painful aftermath of her experience at an event Thursday on sexual violence during the United Nations General Assembly.

“What I survived was not the worst that happened to me. It was what happened after,” Heard said Thursday, speaking to ambassadors and other international government leaders at the European Union’s mission to the United Nations. The event at U.N. headquarters in New York City was organized by Rise, a sexual assault advocacy group, which said it was the first such survivor town hall at the United Nations.

Heard urged ambassadors to support a U.N. resolution enshrining sexual violence survivors’ rights, such as the right to terminate legal ties with one’s assailant and the right to rape kit procedures.

Heard accused Depp of domestic abuse in their 2016 divorce proceedings. (Depp has denied the abuse and filed a defamation suit against Heard this year.)

She said that after coming forward with her abuse allegations she faced daily death threats and “relentless and persistent assaults on my character.”

“And I’m me,” she said, after describing herself as a “relatively high-profile white woman” in the entertainment industry. “Imagine the fate of lower-income women, religious and ethnic minorities…. Imagine how much worse it is for them.”

“The Me Too movement has done a great deal… we need to take our outrage and determination to end sexual violence and we need to codify it,” Heard added. “My story matters. My assault matters.”

Heard was among a handful of other survivors ― including actor Olivia Munn and athlete Sarah Klein, the first known gymnast to be abused by former USA Gymnastics team doctor Larry Nassar ― who spoke at the event.
