Coming Out and moving out this Sunday

And I'm absolutely scared out of my mind. I'm moving in with a friend of a friend. He is gay, and he is helping me out. He doesn't need a roommate but wants to help.My family are Jehovah's Witnesses, and I have been one for most of my life. Not just been one, i've done all the extras, even working at the HQ in NY.They are highly homophobic, and finding out I'm gay will cause them and all the people i grew up with to instantly shun me.I have friends outside the church, not many though. I'm just worried about rent, if they'll sign the car over to me, if I can deal with the isolation.I'm really unsure about it. But if I don't leave now i don't think I will for a long long time.They gave me a letter telling me to do all these things (be home for chores, be home for family worship) all these things that seem small, but are made to control me. I'm working all the time, and I occasionally take time to go out and do stuff.Now that I'm not home as often it bothers them. So they gave me this letter and told me to comply or move out.Frankly, I just anxious, and don't know how to tell them. I'm actually going to move all my stuff while they are at church, I was thinking of leaving a note.I don't want to make this worse than it's already going to be. But Idk what else to do.
