Coming out as Bi

I live in a very very very homophobic area. This has been a huge struggle for me, due to the fact that I just recently came out to my family as Bisexual. On top of that, I also just recently broke up with my girlfriend (I'm a girl as well and WLW relationships are very uncommon here) and im afraid she's gonna leak my Sexuality to my very homophobic friends. I don't want them to know, but at the same time I really wanna come out even if it is in only a small way. For example, instead of a full confession, I could just wear a simple bracelet with the colors of the bi flag, but even then I'm still terrified that I will get shunned or bullied. To add to this stress I know my friends wouldn't support me, and I might end up alone after such a confession. I just don't know what to do and really need some advice. For context, I'm 14F starting high-school and am VERY nervous and this is CERTAINLY not helping.
