I'm scared to tell

I am in high school and my friends are really not okay with gay people. One of my friends in the group came out and now they won't talk to her that much or allow her to stay at there house like they use too. I don't want to come out and become an outcast. I tell them that I am okay with gay people but I am not one. But..... I am bi. And it really feels good to say it.

My parents don't no either. My dad is a pastor, along with the rest of my family, they all shunned my cousin who got married to another women. I don't want to be like that. I am super close to my dad. I would hate for that to change, and i no it would. He is slightly homophobic, but I love him anyways. What should I do I'm scared.
