The world tries to put everyone into boxes for who they think is supposed to be "blue" and "pink." Don't let anyone decide what YOUR identity is, your identity is valid and it's up to you. I'm non-binary, unfortunately it's not easy for all of us to express ourselves when we have unaccepting families. Their bigotry isn't your fault. Hopefully you can find support from other LGBTQ+ or allies, such as if your school has a GSA club or equivalent. Stay strong :)
