I know your feeling when you stand by the wall in the Kingdom Hall. I've been there before I left. I was feeling alone. However, the problem wasn't that other people weren't interested in associating with me; it's just that I didn't take the initiative to talk to them.
Personally, I wouldn't recommend making friends with Jehovah's Witnesses. You're planning to fade, so they will shun you (even though you're not baptised.) You can go out and meet some non-JW people. As Simon mentioned, it's tough, but it is like a muscle.
Also, in your first post you mentioned you were 15, which would make you around 16 now. I'm not exactly your age, but I'm still young—only 18. I just finished high school in June. If you need a friend in your age range, I'm here. I'll send you a PM with my contact information.
By the way, your dad can't track your Internet history by using the router. That's not what routers are for at all. He could track you by installing a program on your computer, which in turn would save your Internet history. However, considering the fact he was threatening your brothers with the router, I'm guessing he doesn't know anything about tracking. I bet he has no idea how to install a tracking program on your computer, so I'd say you're completely safe.
