If your parents are religious and you have different views, psychological separation may be more complicated--fraught with guilt and accusations of betrayal. You may even be exiled or mourned for as if you were dead--not just by your family, but also your religious or ethnic community. Forced separation makes separation more difficult because anger and guilt can keep you entangled with the family and/or community for years--or even a lifetime.
