Caitlyn Jenner made a shocking confession on the series premiere of her new docu-series, "I Am Cait."

"I've had some very dark moments in my life. I have been in my house with a gun and said, 'Let's just end it right here,'" Jenner confessed on "I Am Cait."

Even though her family and friends have been overwhelmingly supportive of her transition, Jenner admitted it hasn't always been easy for her over the years.

Jenner was so moved by the news, she decided to meet with Kyler's parents at their San Diego home.

"It's so hard for young people, because they just don't, they can't see the future. And because of that, they become extraordinarily desperate. We have to do something about that," Jenner said.

It's scenes like this that prove "I Am Cait" is about more than just Jenner's story.

As a writer for Bustle put it, "It's clear that, through this program, Jenner is trying to do some good and spread much-needed awareness. By featuring stories like Kyler Prescott's ... she's giving the spotlight to those who deserve it most."

Ever since news of her transition broke, Jenner has been a public advocate for transgender rights.

She used her acceptance speech for the ESPYs Arthur Ashe Courage Award to deliver a powerful message about the hardships the transgender community faces on a daily basis.

And she's given motivational speeches to groups of transgender youth to encourage them to "live their truth." The issue is definitely in need of awareness. (Video via Vanity Fair)
