So, to start off, my family is incredibly dysfunctional. I’m adopted by my grandparents, but my other siblings live with my biological parents. My younger sister (we will call her Anna) is 15 now and has started going to parties. I consistently warn her not to drink with strangers. The people she is around have reputations that are insanely low (drugs, abuse, etc). Our mother lets her go to these things despite my grandparents and I relentlessly begging her to stop. I have called CPS in the past, but they have not done anything except issue a warning about the conditions my sister is living in. I live around 2 and a half hours away now so the only way I can get updates is through my other siblings.

Recently, she went to a party with these people again, despite me encouraging her not to go. My main method of communication is through Snapchat. I can see her post to “swipe up” for the address to a party. She has taken me off her private story so I can’t see the rest of what happens. My other sister messaged me telling me that there were posts of her friends holding her hair while she’s “acting weird”. I asked Anna why she is doing this and she very strongly denies drinking or doing anything.

I know it’s probably an overreaction, but my sister is 15 years old. She doesn’t go to school except for around 3 days a week. She has a boyfriend every 2-3 weeks and then she drops. All of her boyfriends have really weird reputations, including preying on middle schoolers while he’s in high school. I know she is most likely lying to me about drinking. I’m just tired of constantly trying to protect her when no one else will. I will not speak to our biological mother anymore over this.
