Trevor was shocked at how much support he received from people online, writing them a lengthy thank you post on Instagram.
"Thank you everyone for your support. I cannot express that enough and I could not have gotten this far without you guys! I know a lot of you have called and emailed my school board - flooding their voicemails and inboxes.
Thank you for standing alongside me to create change so that students like me can express ourselves in authentic ways in school and focus on our studies rather.
As well as ending the gender norms that society has oppressed on us. Please continue to call and email but for those of you who want to challenge dangerous gender stereotypes you can join me in painting your nails and rocking them all over Texas and the country," he wrote.
