Iwonder,
Everyone has given you really good advice. You're not "stuck" in the religion. If you're an adult, you have a choice. Its a very controlling religion that makes you feel as if you don't have choices and that the world will eat you alive. None of that is true.
Liars, drug users, alcoholics, fornicators, adulterers, pedophiles, perverts in general...you find them in the world and you will find PLENTY of them in the congregation. Not all of these folks are DF'd before the congregation, so much goes hush-hush depending on who you are, if your daddy is an elder or if your family has money so most in the congo don't even know whose in their congo.
Don't let the world scare you. But like someone else said, friendships outside the org are different. People actually talk to you instead of at you. Open up a little bit and share things about yourself. The first time I went out with a group of non-witnesses after leaving, it felt soooooo strange. It took time to figure them out and guess what...they are not the devil.
It takes time. I hope everything works out for you.
