I have a dear friend who means the world to me. Over a period of 10years (maybe more) she has been Gas Lighted by her daughter. The situation is so out of control she no longer knows her own mind, will lie to protect her daughters behaviour, can not see that her daughter is negatively affecting her relationships with her dearest family member. It’s so sad. I made the mistake of calling the daughter out, which has made me the latest target. Any advice to help a dear friend would be very much appreciated
