I sympathize with you and sorry to hear about your mother but I understand where you are coming from. When I was a little girl many of my neighbours changed religion and my mother did not and we had a difficult time with them. If we dressed in shorts or attend our church we were ridiculed. These people were our relatives but they were ignorant and were brain washed. We moved and left them with their lives and we noticed their lives began to crumble. Just leave them to God and he will do the rest.
