Questions about coming out

Hi I feel like I have gay tendencies but still like women so I'm bisexual. So, a few questions specifically to people who have come out as gay. 1. Who should I tell 2. How should I tell people 3. How I should I get ready for people's reactions* thank you for all responses I might not see it immediately but I will eventually.*so the reason I ask this is because I have a SUPER catholic family and I'm worried . Also I have some friends who are catholic and have some scary opinions on gays and I'm worried about that as well
