We'll definitely see Caitlyn Jenner having a lot of fun in her new docuseries, "I Am Cait," but she also plans to take on hard-hitting issues in some episodes. The 65-year-old reaility-TV star has been very vocal about her hope that her show will "do some good" and bring awareness to issues facing the transgender community. 

Just days ahead of the show's premiere Sunday, E! has released yet another new "I Am Cait" clip. In it, a bare-faced Caitlyn is shown worrying about how she will utilize her newfound platform as a transgender celebrity. The former Olympian appears visibly stressed about the violence transgender people face day in and day out, saying, "We don't want people dying over this." The 50-second video shows her lying awake in the wee hours of the morning questioning her ability to bring awareness to this often underrepresented population and praying she'll "get it right."

"What a responsibility I have toward this community," she says. "Am I going to do everything right? Do I project the right image? My mind's just spinning with thoughts. I just hope I get it right."

Since introducing herself (formerly Bruce) to the world as Caitlyn on June 1, the reality star has been working closely with the Human Rights Campaign and fellow trans woman Janet Mock's campaign, Girls Like Us. She shared a tweet about having met with the group during a brief trip to San Francisco on June 5. Caitlyn did not divulge much information about the meeting, but promised fans that more details were coming. The following day she penned a blog post outlining some statistics on violence against transgender people.

This is the first serious clip from the show. Others have shown Caitlyn partaking in the more light-hearted bits of her new life as a woman. The former "Keeping Up With the Kardashians" star allowed E!'s cameras to tag along as she made her first trip off her property as a woman, went shopping for women's clothes for the first time and even revisited some of her old favorite hobbies like riding motorcycles because, as she points out in one preview, "Girls do that too!"

"I Am Cait" premieres Sunday, July 26, at 8 p.m. EDT on E! Check out the most recent preview below.
