Transgender Teen Jazz Jennings' Older Brothers Have Her Back: 'Embrace the Change and Accept It, You'll Do Just Fine'

In an exclusive sneak peek at this week's episode of her TLC reality show I Am Jazz, the 14-year-old expresses some concern about starting high school – and in true older-sibling fashion, her 17-year-old twin brothers are quick to offer her support.
"I'm just happy to get away from my life, you know," Jazz tells her family during a car trip to Gainesville, Florida, where the group is headed to help Jazz's oldest sibling, Ari, move out of her college dorm.
Jazz goes on to reveal she is "worrying about high school approaching."
"I think the high school transition can be overwhelming, if you let it be overwhelming," her brother Sander says. "If you just embrace the change and accept it, just like you've always done with everything, I think you'll do just fine."
"Jazz sometimes struggles with stress in life," Griffen says to the camera during an interview. "She has a lot of stuff going on … more than most young girls her age."
"So she needs help," Sander adds. "And we're her big brothers."
Back in the car, the family discusses one of the twins' friends who "didn't understand" Jazz's experience and thought "being transgender was a choice."
"But hasn't he known me for so long?" Jazz asks. "I thought he would understand it, like, if he knew so much."
"We talked about it," Sander says. "We explained to him what it was like, and he was like, 'Wow. I didn't even know that.' "
In addition to supporting Jazz, the twins are advocates for the entire transgender community.
"It's not an easy path being transgender," Griffen says to the camera. "Like 40 percent of transgender people try to commit suicide. It pushes us to make a change – to make people support her and any transgender person."
I Am Jazz airs Wednesdays at 10 p.m. ET on TLC.
