The finale of docu-series "Lindsay" on Oprah Winfrey's OWN network left everyone in shock -- the "Mean Girls" actress revealed that she had a miscarriage.

Lohan explained why she previously had to take a couple of weeks off from filming the show. "No one knows this, I had a miscarriage for those two weeks that I took off," she said. "It's a very long story." Lohan did not reveal who the father was when she made the confession.

When asked recently what it was like to watch her own series, the 27-year-old actress admitted it was difficult, especially the fact that people were frustrated when she took a break from filming. "That's why on the show when it says she doesn't want to come down, I couldn't move, I was sick. Mentally, that messes with you," she said. "Watching this series, I just know how I felt at that moment and I can relate to that girl, which sounds kind of crazy, but I'm like, 'Oh my god, this is really sad. Who's helping her?'"

"There was a lot of going on in my life then. I cried so many times watching it. Because I don't see it as me -- it's strange. It's weird."

In addition to the dramatic ending, Lohan opened up about her drug addiction. "Even if it's not my intention to lose everything I'm now working for, that's what this addiction will do to me. It's really fucked up disease and it's really scary. It's f*cking terrifying," Lohan said. "I may have addictions to certain things in life, but I'm not essentially your typical addict -- that's not who I am, I'm not the kind of person."

"I know the difference between right and wrong, it's stupid and idiotic, and what's good and bad," she continued. "I know that, I was raised well by my parents, and I've seen it."

Lohan also said that she was the person helping others get off drugs. "There are drugs that people say I've done that I've never touched, that I know people that have done that," she said. "I've tried to help a lot of people to get away from that sh*t, and to find a balance in life -- to be OK with just being OK."

She then discussed how she was able to change for the better, even admitting that she "blocked so many people on [her] phone" who she realized were bad influences. "It was really intense -- I saw my whole life in front of me. I saw myself die -- it was intense. I saw myself being born," she said. "I had to let go of past things that I was trying to hold on to that were darkening my life. I feel different ever since then. Just being OK with the wreckage of my past, and letting go and being fresh."
