Why can't have a normal life as a teenager and be able to make friends that share similer interest as me other then the fact that we are in the same religion?
That's the nature of the JW religion... and a large part of why it is good to get out of it. You can find friends in all sorts of places, and hopefully they'll be understanding about the crazy parents... Just don't push your mother too much until you have an escape plan. If your parents think you're going south, there might (depending on the parents) be a good possibility of them kicking you out.
Getting a car/job would help a lot... Though I got past that particular one by getting a girlfriend with a car and lying my butt off about everywhere I went. (Don't lie... It's bad)
