I didn´t grow up surrounded by jws, but when I joined them, I cut all my associations with people who were not JWs. After almost 15 years being a JWs, all my friends outside the borg had disappeared. The way I dealt with this was by doing what I always wanted to do: studying. The first year after my being DA'ed, I worked 7 hours a day and I attended clases 5 hours a day, and then I have to do my homework and prepare the classes for the next day. I was too busy to think about how lonely I felt! And the good thing is that I was enjoying with the classes, I had always felt that the "theocratic education" was not enough for me. Furthermore, attending classes with people 13 or 14 years younger than me was a wonderful experience. To be with all these "worldly" youngsters helped me see people in a balanced way, that there were good people outside the borg. I even went partying with them sometimes (I looked like the father of the group, but I didn´t matter).
Another thing I learned is that I learned how to enjoy my loneliness. Now I don´t have many friends (buy they are true friends), and I like socializing, but now I need some moments for me. I learned to feel comfortable with myself and not feeeling afraid if I don´t have any plan to go out on Saturday, I know I can enjoy a good evening with some music, a good book and preparing a nice dinner for me, that´s it.
