Well first, you don't have to tell anyone unless you want to. Don't feel pressured into it, although I know that's alot easier to say than to do.

You're right, it's probably best to start with friends you trust and believe will be accepting. Especially if you decide to come out to family despite the risk of likely not being ok with it. It's good to have people on your side in case things don't go well. I understand wanting your family to know, but sometimes it's best to hold off on telling them if you think they will have a bad reaction, and especially if you still live with them. For example, my family (specifically my mom). My mom is totally ok with gay people. She says there's "no such thing as bi," and that it's "just being perverted." The problem is, I'm bi. So I haven't told them.

You said 3 people know....are they friends? How did you tell them?
