Lewinsky, now 40, was in her early twenties when she became the infamous blue dress and beret-wearing muse who engaged in sexual relations with the president and then endured a colossal backlash that nearly drove her to suicide.
After years of being turned away by potential employers and ridiculed online, she decided to write her version of events in this month's Vanity Fair magazine.
"It's time to burn the beret and bury the blue dress," Lewinsky wrote, in excerpts posted on the magazine's website.
She said her radio silence was so complete for nearly a decade that rumors swirled that the Clintons must have paid her off to keep her quiet.
"Nothing could be further from the truth," she wrote.
It is time to stop "tiptoeing around my past -- and other people's futures," she said, in a possible reference to former secretary of state Hillary Clinton's expected White House run in 2016.
While the Clintons moved on, Lewinsky became an American outcast, even as she came to regret one of the most famous political affairs in US history.
"Sure, my boss took advantage of me, but I will always remain firm on this point: it was a consensual relationship," she wrote.
"Any 'abuse' came in the aftermath, when I was made a scapegoat in order to protect his powerful position," she added.
Instead she applied to various communications and marketing jobs, but the employers balked, claiming her "history" made her the wrong person for the job.
The anxiety made her suicidal at times, she admitted.
