Bisexual 👩🏻👱🏻‍♀️👱🏼

Hi everyone. This has been on my mind for a really long time now. I think I've always known that I'm bisexual, but I just need to say it to someone. I'm from a very small town where sexual orientations other than straight aren't widely accepted. My best friend came out at bisexual as well, and received a lot of hate for it. I wish I could tell her, because I've had a crush on her now for about 5 years but I'm too scared that she won't feel the same about me. I've also got a crush on my best friend here at college but I know I'm not her type. Any suggestions here? Should I just let them go or should I tell them? I don't want to ruin my friendships but I'm also kind of done hiding in the closet with the people I'm close to!
