Hey Skyler,
I'm Grayson, 15 y/o FtM as well. I'm sorry for the situation that you're in, but like the others have said, I think dropping some hints around your friends/family to see what their thoughts are would be a good idea. I've done that with my friends, and they made it pretty clear that they won't be very accepting. They've gotten a little better since then, but I'm still not ready to come out to them either. I do have a couple friends who are awesome with it though. Once you find the right support system, you're golden.
Even if you choose not to do that or can't find some support, we're all here for ya man. At the worst, it's just a waiting game until you can find the right time/people to come out.
Good luck,
-Grayson
