Purza, This may not be a connection, but I have a 16 year old young friend who left the JWs with her family at age 12.
She has seemed to enjoy birthdays and other such celebrations to the hilt. However, recently a "friend" has encouraged her
to come study at the KH. I realize this girl has been taught nothing, absolutely nothing, other than JW teachings. When they
left they left. Period. Did not attend anywhere else. She is questioning God, etc. and hears kids at school talk about their religions and feels left out. Could this be similar to your daugher's experience? If so, I strongly suggest that you sit down and talk with her, even show her Christian websites that she can learn from, etc. Read and look things up together. Kids need guidance, esp at times like this.
Just a possibility....Good luck to you and your daughter!
