'The Hills' Star Lo Bosworth Reveals She's Been Battling Crippling Depression

Former The Hills star Lo Bosworth told followers of her blog that she secretly battled anxiety and depression for more than a year.

The blonde reality beauty, 30, posted her very emotional story on her The Lo Down blog, calling it "The Great Depression."  She also provided an accompanying YouTube video.

Bosworth wrote, "2016 wasn’t only just the worst year ever, it was also the year I turned 30, founded my own feminine wellness company Love Wellness, and brought an amazing puppy home. So not all bad," she wrote. "Light does find way of shining through the darkness. And what is the darkness I’m referring to? Crippling anxiety and depression at the hands of a severe vitamin deficiency that went undiscovered for 16 months."

The Hills had its final season in 2010. At the end of 2015, the star revealed she started "feeling off" with a "racing mind, impulsive behavior, insomnia." In 2016, she tried therapy sessions and anti-depressants to try to solve her meltdown.

"I feel OK for moments of time, and then plunge back into the darkness again and again. The anti-depressant cycle is a vicious one — especially if you don’t actually require one, but that moment of enlightenment won’t arrive for another nine months. Up and down, up and down. Tears, moments of extreme highs, confusion about why you don’t feel completely back on your feet after the standard 4-6 weeks of allowing the meds to 'kick in,'' she wrote. "Making changes and adjustments to medications more than four times. Exercise helps, my relationship helps, my family helps. But, the underlying, creeping feeling that there may not be a silver bullet to my problems, and that this state of disarray may be the new ‘me’ keeps me feeling stagnant. I wouldn’t wish my 2016 on my worst enemy."

Now the ex-The Hills star, who is always part of "Where Are They Now?" stories about the cast, takes a daily vitamin regimen and is back to normal.
