When 17-year-old Gabrielle Diana, a transgender teen in Ottawa, began transitioning three years ago, she felt uneasy.
"I was just a gay boy experimenting with my image, but now I'm a transitioning woman, almost getting to the next step of a major surgery that I never imagined would be in the cards," Gabrielle wrote next to an Instagram post featuring photos of her transition.
Today, however, she feels incredibly joyful: "I've never been more happy and I can't believe this is fucking real," she wrote.
Gabrielle's Instagram post, featuring the hasthag #MomentsOfMyTransition, went viral on Tuesday. It inspired other transgender teens to share similar photos, with the hashtag #MomentsInTransition.
A recent study found that transgender adolescents who express their identities experience positive mental health.
"It's our way of saying, these are moments in our transition that defined us even more, and we are gonna wear these moments for our own desire, not to please anyone else," Gabrielle told BuzzFeed News as the hashtag went viral.
Here are 13 teens sharing their incredible transition experiences on Twitter.
