Snakes,
Great thread. I can understand a bit of what you're going through. Its part of the normal process and while that doesn't make it any easier, at least you know you're not the only one that has those feelings. I too am finishing my degree (just a few more classes to go!!) and we're around the same age. A few years ago when I started realizing that the WTS isn't "Gods channel", I started slowly withdrawing from my JW friends. Like you, I haven't really replaced those folks and turth be told, they really weren't that close. My wife & I have a great relationship and that's really the only thing that has kept me sane. However, I really don't share with her the pain of losing my religion although I have shared my doubts with her. Its really no-mans land but that's road I've chosen to walk.
I'd encourage you to keep "your eyes on the prize" (sorry I couldn't resist). Throw yourself into your school work and continue getting good grades (which I'm sure you're doing). Once you finish, get the hell out of Dodge. I think you said you're looking at what, 6 months? You can do it. Then, you can really start building a life. When you land at your new home, go in with the attitude that you are going to meet and make good friends. Get involved with the community, join a club, go out with coworkers or neighbors. You'll figure it.
The great thing about these discussion boards is that you can vent even if its just reading others posts. Continue using it as a lifeline. I'm available if you ever want to talk.
