Hello breezy, and glad you entered into this community of people that understand what you're saying. That said, I'm an older 'born in' but my story is quite different. You will, however, find plenty here that are at very similar points of life.
What I can maybe offer is the thought that this story, your life and all, is such a bigger picture than the small insullar picture you have been shown by your JW upbringing.
The so called 'world' is not an altogether evil place. It's full of compassionate people and wonderful adventures....in short, you were lied to. There is so much good 'out there'. Choose your associates wisely and with care. There are many that are good and worthy. Prove mostly to yourself these things and then let your family and old friends see you doing well. That is the best answer and defense to give to them without really saying anything. Yes, I know...the shunning sucks! It is on them.
