Lena Dunham was one of Hillary Clinton's most vocal supporters during the election, and now she has written a letter responding to Donald Trump's victory.

Dunham wrote a letter in her Lenny newsletter on Friday explaining how "heartbroken" she was to see Clinton lose the election to Trump. The Girls star admitted that she "never truly believed" Trump could win and when it was clear that things were heading this way on Tuesday, she cried and broke out in hives.

The actress recalled being threatened throughout the election, having been called various names and receiving death threats. She hoped that Election Night would ultimately let her and her fellow Clinton supporters have the last laugh, but it was not to be.

"We kept going, thinking these were the dying moans of the dragon known as the patriarchy being stabbed again and again in the stomach," Dunham wrote. "We believed that on Nov. 9, they'd be licking their wounds while we celebrated. It is painful on a cellular level knowing those men got what they wanted, just as it's painful to know you are hated for daring to ask for what is yours. It's painful to know that white women, so unable to see the unity of female identity, so unable to look past their violent privilege, and so inoculated with hate for themselves, showed up to the polls for him, too."

Dunham also admitted that she was truly "heartbroken by the system for the first time at the age of 30," and what a privilege this was compared to those from minority groups.

"So many people - those in the prison system, those with undocumented American relatives, those who are trans, who are queer, who are people of color, who are Muslim, who are trying to prosecute their abusers - have felt the crushing failure of the system over and over again," she wrote.

She suggested taking until Sunday to grieve Clinton's loss and then getting inspired to fight for social causes. "So no, the work isn't done. It is only beginning."
