Monica Lewinsky was only 24 years old when she found herself humiliated in one of the Internet's first cases of mass public shaming.

Now, she's asking people to "click with compassion" and ask themselves, "would you say that to someone offline, just as we're sitting here?" in a new anti-cyberbullying PSA.

Lewinsky commanded the nation's attention in 1998 when the news broke of her sexual relationship with then-President Bill Clinton, which led to years of endless torment and ridicule.

"There were many times over the last two decades when I wasn't sure I would make it," Lewinsky explained on CBS Monday, "and so I can really relate in a way to how a lot of people are feeling in today's world, even though it's for different reasons and now we have social media."

In order to help those who find themselves at the center of cyberbullying today, Lewinsky is partnering with In Real Life campaign's mission to urge Internet users to #ClickWithCompassion.

"This is very much about showing the disparity between how we behave online and how we behave offline when we're face-to-face," she said.

Although her scandal unraveled in a time before social media, she said that she can "relate" to those who find themselves at the center of a online attack. On CBS, she encouraged people not to say things online that they wouldn't say to someone sitting next to them, and said much of the "clickbait" out there is bullying people and should be avoided.
