Mary Trump, former President Donald Trump’s niece, wrote in her newly-released book, “The Reckoning: Our nation’s trauma and finding a way to heal,” that she sought treatment for PTSD after her uncle won the 2016 election.

The period following her uncle’s victory severely impacted her mental health, according to an extract published by The Sunday Times. “For months, I alternated among states of dissociation, rage, and befuddlement,” she wrote.

In April 2017, Trump said, she was in “the worst psychological shape” of her life, and, some months later, she decided to check herself into a treatment center in Tucson, Arizona.

The center specializes in PTSD, she wrote. “I would be there for weeks, excavating decades-old wounds and trying to figure out why my uncle Donald’s elevation to the White House had so undone me,” Trump added.

While at the treatment center, Trump said that her first few days there were filled with “rage” and anger. “Outside of group and individual therapy, I didn’t speak to another human being for the first five days I was there,” she wrote.

“It was really impossible to wrap my head around it all,” she told The Sunday Times. “At least once a day, I would have this moment where it would dawn on me what had happened. It was surreal. Because I felt such shame, that the country had so debased itself.”

The book, her second about her uncle, examines America’s national trauma that she claims has been “exacerbated” by Trump’s administration, according to her publisher.

In another extract, Insider previously reported, she wrote that her uncle used the phrase “it is what it is” when she pressed him on why her father’s ashes were to be buried in the family plot instead of scattered off the coast of Montauk.
