Hello everyone. I'm here looking for advice on how to handle my sister. She is 15 going on 16 in December. She used to be a bright level headed person, but she is changing and I don't know how to talk to her. This past Christmas she stole two Visa Gift cards from my husband and I we received as gifts. She disrespects our parents and they do not parent her as they did with me (I feel they are trying to be her friend and be nice). Just recently I learned she has started sneaking out at night, smoking pot, taking pills, and having sex with her boyfriend. My mom did not tell me how they were trying to handle it. My husband and I have tried to hold my sister accountable for things (recently posting revealing photos and crude language online.) She only blows it off and says something like, "Okay then." I worry if I talk to her she'll do something drastic (she says when she fights with our mom she thinks about suicide. not sure if she's being dramatic or serious, but I treat it seriously). Today she is going to a Christian camp and I pray God guides her in this time. (She has been before and loves going, but not sure if it is for the message or social setting). How can I try to talk to her about this?
