Should I come out?

I cannot come out to my family, and I cannot come out to my close friends. I never plan on coming out to these people (because I feel like my friends will treat me differently even if they don't mean to, and I can't even imagine how my family would react...because I'm bisexual it'll be easy to hide it, tough luck if I fall for a woman in the end, though), but I really need to tell someone. I know a friend, she's a good friend but not a "close" friend per say, and I know she's really involved in the LGBTQ+ community, and I want to tell her because I want to tell [i]someone[/i].

Should I do it? I'm afraid I'll regret it.
