Well, I think first you have to assess how important your friendship is, and how supportive they are of LGBT people. Some people will refuse to be friends with people who can't love every part of them, while some people still need their friends and would rather stay in the closet to be with them. If you want to know their views, just bring up a recent event and see their reactions. If they react the way you want and you really want to tell them, then go for it. Just say you have something important to tell them, and then you can say it, and that's it really. Even though it feels so difficult and nerve wracking. Good luck!
Come out to a close friend you know will accept you then from their they can support you when you feel ready to come out to the rest of your friends.
Hi :3 If you have any LGBT friends, then that's possibly the place to start by telling them. My pansexual/genderfluid friend was where I started. If not, decide whether you would feel more comfortable telling them all together, one by one, or a combination of both. If you don't feel comfortable face-to-face, try writing a letter. All the best :3
