"Am I going to do everything right? Am I going to say the right things? Do I project the right image?"

Caitlyn Jenner can't sleep in a new clip from I Am Cait, her eight-episode docuseries premiering on July 26.

Jenner takes her responsibility as a transgender spokeswoman very seriously, and she confesses her concerns about the weight of that responsibility in a raw, vulnerable chat with the camera at 4:30 a.m.

"I feel bad that these [people] — especially young people — are going through such a difficult time in their life," says Jenner. "We don't want people dying over this. We don't want people murdered over this stuff."

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