Turn the car around and head back in the right direction.
((((hugs)))) to you, I know exactly how you're feeling because I've been there as have many on this board. Don't worry about how you feel right now, start making plans your life isn't over by any means. There's plenty of fun to be had, new friends to make, places to go, people to meet.
If you have left and now have no belief in God, or you still have a faith but don't know what to do with it don't worry things will settle down.
You can always come here for a chat, a rant, or just some hugs don't worry because there will always be someone about.
Just remember the W/T have lied about everything including people out in the 'world'. People are fine, you will make some good friends and at least they won't be conditional.
