Lauren Conrad sad over a series of serious disappointments?

Lauren recently broke down in tears at her Hollywood Hills home, wallowing in the misery that she feels her life has become.

"She's an emotional train wreck," a source close to LC tells Star. "She usually doesn't lose it like that. But her life has spiraled out of control, and once she opened the floodgates, it was all over. She just crumpled, putting her head in her hands and sobbing."
