Caitlyn Jenner Goes Makeup-Free in Opening Scene of 'I Am Cait'

Caitlyn Jenner is so committed to showing what her life is like as a transgender woman that she's even willing to film during her sleepless nights.

The 65-year-old former Olympian opens her eight-episode docu-series, I Am Cait, in a way many viewers probably wouldn't expect -- especially if you've watched the glitzy Keeping Up With the Kardashians.

Appearing makeup-free, Caitlyn talks to a handheld camera while in bed, admitting that she's having trouble sleeping as her heart is heavy thinking about those transgender individuals struggling with their journey.

"I feel bad that these [people] -- especially young people -- are going through such a difficult time in their life," she shares. "We don't want people dying over this. We don't want people murdered over this stuff. What a responsibility I have towards this community."

Continuing to show her vulnerability, Caitlyn confesses that she sometimes questions her impact on her community. "Am I going to do everything right? Am I going to say the right things? Do I project the right image?" she says. "My mind's just spinning with thoughts. I just hope I get it right. I hope I get it right."

I Am Cait premieres Sunday at 8 p.m. on E!, but ET got an advanced screening of the docu-series!

Viewers can expect an honest look at the transgender struggle with less drama than other Kardashian-Jenner reality shows. That being said, members of Caitlyn's famous family -- Kim Kardashian, Kanye West, and Kylie Jenner in person, Rob Kardashian on the phone -- do appear in the first episode, but the cameras never take focus off the star of the series.

As ETonline editor Stacy Lambe points out in his review, I Am Cait "mirrors Caitlyn's ups and downs with other transgender stories not normally exposed to film crews, let alone displayed on a network like E!"
