Hi LHS123, Encouraging your daughter to make more non-JW friends is the best course of action for you. You can also counsel your daughter about the pros and cons of posting on social media and not talking about her non-JW activities with JWs.
Also, I do not feel that the WTBTS doctrines have helped your daughter. How could the WTBTS doctrine of refusing blood help your daughter if she was in a car accident and lost 6 pints of blood? How does refusing to go to college to increase opportunities for her help her? How does avoiding non-JWs to be played like a yo-yo with JWs help your daughter form meaningful relationships? How does pioneering for a printing, print distribution, and real estate property corporation instead of having fun with friends help your daughter?
How has the WTBTS benefited you and your family? I can counter those thought-stopping platitude with how the WTBTS has victimized you and your family with BITE manipulation techniques.
Peace be with you and everyone, who you love,
Robert
