Caitlyn Jenner is starring in a new documentary.After appearing for several years as Bruce Jenner on Keeping Up With the Kardashians, the 71-year-old transgender aspiring politician can be seen in Netflix's Untold: Caitlyn Jenner, which features her unlikely path to Olympic glory and highlights the challenges she faced as she learned to embrace her true self.Below you'll find some of the surprising revelations made by Jenner amid the special, including a statement regarding the confusion she felt throughout her life while presenting as male.1. Caitlyn Jenner Was Always Confused"I've just always dealt with confusion in my soul," Jenner admitted in a clip from the documentary, via the New York Times. "But when sports came around, it became the place where I could shine. That changed everything."According to Jenner, who came out as a trans woman in 2015, she used sports as a crutch. Rather than address her lingering identity issues, she dove head-first into being the best athlete she could be in an effort to distract herself from the hardships she was facing as an individual.2. Caitlyn Jenner's Issues Fueled Her Success"I've always had these issues going through me. But without them, I don't think I ever would have accomplished what I did," Jenner explained.Although Jenner battled feelings of insecurity about who she was deep inside throughout the many decades she spent outwardly presenting as a man, she was able to successfully translate those issues into passion for her craft, which was all things sports.Throughout her younger years as Bruce, Jenner wowed the world with her physical ability, all while facing inner demons within herself.3. Caitlyn Jenner Believes Bruce Was Nothing More Than A 'Character'Looking back at the time she spent as Bruce, Jenner said that she, decided to focus her attention on creating the "character" known as Bruce instead of working through the issues she felt over her identity."I trained 365 days out of the year because I needed to prove myself," Jenner explained, stating that she felt that if she could achieve certain accolades in the world of sports, it would somehow take away the pain she felt inside.4. Caitlyn Jenner Hoped Success As An Athlete Would Absolve Her IssuesAccording to Jenner, she truly felt, years ago, that if she were able to accomplish a lot of things, and further establish Bruce, as the greatest athlete ever, he would no longer question who she was as a person."The winner of the decathlon is the greatest athlete in the world. They give you that title. That's what I want, right there. If I can win an Olympic gold medal, I can prove these issues don't exist," she thought to herself, back then.5. Jenner's Success Couldn't Mask Her Desire To Be A Woman"I was still the same old person with all the same old issues," Jenner recalled.As we now know, Jenner ultimately learned that being a "he" wasn't for her. And in April 2015, she confirmed to the world that she would be known as Caitlyn Jenner, from then on.Since then, Jenner has been thriving as a female as she resides with rumored girlfriend Sophie Hutchings in Malibu and attempts to get the people of California's vote for the next governor of the state.
