Monica Lewinsky returned to the news Monday as she joined Twitter, as her first tweet simply read #HereWeGo.

Calling herself "patient zero" for cyberbullying, Lewinsky said she was joining social media in an active way to fight abuse and bullying.

Coupled with the new Twitter presence, Lewinsky gave her first public speaking appearance in a decade, and fourth ever, addressing the Forbes 30 Under 30 Summit at Philadelphia.

Infamously known for her sexual involvement with President Bill Clinton in the late 1990s, Lewinsky kept a low profile for years. However, this May she said she was tired of her bad treatment in public and was going to stick her head above ground "so that I can take back my narrative and give a purpose to my past."

This take back the past narrative quickly took a turn through Vanity Fair. Lewinsky gave a breakout interview there in May.

Her new Twitter handle @MonicaLewinsky came alive shortly after 6 a.m. with the HereWeGo hashtag that got more than 2,500 retweets and a profile that described herself as a "social activist, public speaker, contributor to vanity fair, knitter of things without sleeves." She gained more than 30,000 followers within nine hours of joining Twitter.

A second tweet around 7 a.m. said Lewinsky was excited and nervous to be speaking at the Forbes Magazine Under 30 Summit in Philadelphia. 

Speaking to more than 1,000 millennials at the conference, Clinton's former mistress, now 41 years old, said she was "Patient Zero" in the world of cyberbullying, "the first person to have their reputation completely destroyed worldwide via the Internet."

Noting the lack of Twitter, Facebook, Instagram and social media outlets in the late 1990s, Lewinsky said emerging web platforms along with gossip news and entertainment websites did the hatchet job even with the relative slowness of dial-up Internet.

Lewinsky said the 1998 scandal that resulted in Clinton's House of Representatives impeachment and Senate acquittal submerged her with feelings of deep shame and suicidal feelings. She blamed the then-unknown Drudge Report and the subsequent Starr Report release for being out-of-context and hurtful.

Lewinsky said she began thinking about going public in the fight against cyberbullying following the 2010 death of Tyler Clementi, a Rutgers University freshman who committed suicide after being cyberbullied about his homosexuality. She later met his parents.

Saying she had survived the abuse, Lewinsky added she wanted to put her suffering to good use and give purpose to her past. For the speech transcript, visit here.
