if that is who you are, then people will need to accept that and im sure they will. I know it must be a really scary thing but your sexuality does not define who you are as a person and doesn’t change who you are either. You will still be loved and cared for the same by your friends and family. Your mom is your mom, she will love you no matter what. As for friends, if they judge you or treat you differently, they aren’t very good people or friends and you shouldn’t have someone like that in your life. I think coming out will take a huge weight off your shoulder and will eventually be the best thing for you.
