New York City is home to the largest LGBTQ youth population in the country.
More and more teens and young adults now identify as non-binary and gender non-conforming, but many — especially parents — don't really understand what that means.
Vanessa Mckenna, 19, was named John at birth. She came out as a transgender woman last year and began her transition this summer.
Louie McDonnel has a similar story.
"When I was younger, I was always playing stereotypical boy sports, but I always felt something was off," McDonnel said. "I realized I was transgender and came out to my parents when I was 18."
Their decisions to come out came with consequences.
"Everywhere I go people are going to stare at me," Mckenna said.
Dr. John Steever, from the Adolescent Health Clinic at Mount Sinai, has treated nearly 600 gender non-conforming patients, same as young as eight.
"My goal is to help them achieve the perfect alignment between body and mind," Dr. Steever said.
