You will soon find that the "horrible worldly" people are not that horrible at all; they are actually quite nice and friendly!
So are we, sort of !
Don't worry about your future, and having no friends! Just give it time, brother! You will never look back to that horrible religion, and it's double standards. I know exacly what you mean about those "runins!"... LOL!
Being without friends is very tough, I only have a very few left myself. Fortunately, my JWD buddies are always around to amuse, help, whine, lend an ear, all with complete understanding of the JW culture. Couldn't have made it thus far without 'em. They'll be good to you, too.
