I want to come out so bad😭

I'm in a relationship (with a man) and he knows I'm bi sexual. I want to come out so bad to everyone else. I didn't even come out to him. He figured it out on his own, and I told him, yes I am. I want to tell my parents and my family and friends. I want to tell everyone on social media but I'm so scared of what everyone will say. I'm so scared of what his family will say. I'm so scared of back lash and losing people in my life. I want to come out so bad but I don't know how and it's really bothering me😔😔
