(Vent) Coming Out

I'm bisexual, and my parents are Christians, so I feel really nervous coming out to them. I know by older brother will support me if I do come out, but I have no idea how my parents will react. I don't think they'll kick me out of the house or something like that, but they'll still judge me for it and tell my aunts and uncles. One of the uncles on my mom's side feels like he's definitely homophobic, but everyone else I'm unsure of, and I don't think I could ask anybody without them becoming suspicious of me. My best bet is to come out to them once I'm out of the house and financially secure, I guess. I just feel so alone right now.
