Idk. I think this young lady is in a spiritually toxic situation at her current church. I'm willing to bet if you put her in a church that's Bible believing, Bible teaching, truly about developing their relationship with Christ, and the members treat each other like brothers and sisters, if she was saved to begin with, something will be rekindled inside of her. If not, you could get back to her in a month or two and she'll be like, "nice church, very nice people, made some good friends, nice music, nice sermons, but still church is...meh." (Either that or perhaps there's a TON of church hurt here that needs to be dealt with.)
People who are more mature in Christ can think more clearly in these situations like, "this situation is toxic for me. I know I have family here, but it's hindering my relationship with Christ. Time to move."
I kinda feel that if this young lady has had such a hard time making friends in the past, the prospect of going to somewhere else with people who are supposed to believe the same thing, and have the same morals as the people who are hurting her scares her. Should she be dependent upon people to guide her through her relationship with God? No, but it seems like she's at that point where she would need a guide before venturing out on her own.*
(* = based on a situation I had with a friend and a situation from my childhood. My friend asked me how to pray and didn't know how to answer in a way that was helpful because I was taught how to pray coming up. IMO, praying is easy however people who haven't done it before need to be walked through it. You can't just say, "Geez! Bow your head and close your eyes and say stuff!" cause not only is that inaccurate, it doesn't teach anybody anything, and it just pisses of the person. Also, when I was younger I was hesitant about studying the Bible by myself because I figured it would be easy to misinterpret stuff and I didn't want to learn incorrectly so I opted for Bible Study. Obviously she can't go to Bible study where she's at and I think she need a friend to help her move on to another church)
