Even from a young age, I was sexualized,” Barton wrote.

Barton began recalling her time working on 1999’sPups, which also starredBurt Reynoldsand Cameron van Hoy.

The movie blew up in Asia, and I became a strange sex symbol over there.

I was 13," she wrote.

The actress went on to address her time playing Marissa Cooper onThe O.C.as an 18-year-old.

“I had a few breakdowns,” Barton shared.

“But no one questioned why I was having those breakdowns.

I became a target of nasty attacks when I was clearly expressing signs for needing help.

Just because the pain isn’t visible, it doesn’t mean it isn’t there.”
