I lost a "heritage" due to my being a 3rd generation JW. I no longer see people that knew me as a baby, that knew my Mum when she was alive, or that have been friends with my family since the 50s.
It's damaged my relationship with my sister and several cousins. My sister still talks to me, but I'm looked upon as being worldly and not someone for my niece to look up to.
I've lost "friends" but looking back, most of them were never friends in the truest sense.
I've lost an entire social base. As a good JW, I never made friends with "worldly" people, so since I left, I have had to start making friends from scratch.
