My girlfriend came out as Trans* last weekend and I've never been happier for her.
She's been struggling a lot with her mental health and sense of self, so i'm really relieved she finally felt comfortable enough to confront her family about her identity and even though they don't accept her, she's stolen a piece of my heart that i hope will fill that void. She's got me, and she always will.
We've been together almost a year now and she may get teased by people but to me she's really fucking fab. (Plus, she's a Slytherin so that's always a bonus..)
I don't really know why I'm sharing this apart from it's okay to be out there and different; there will be people who will accept you unconditionally, who will love you even more for not being afraid of your own identity anymore.
Be comfortable with yourself, you're the only person you're ever gonna have to live with
