So confused- help? New to this. Ive been a guardian for less than a year.

I take care of my 14year old sister. We just moved into our actual first house. Since her old time friend is close by, I told her she could invite her friend over. She’s told me her friend’s dad is abusive to her mom- so I don’t feel comfortable letting her sleep there. Friend also has older brothers in the house that have gotten younger girls pregnant. Every time I offer for her friends to come over, she starts flipping out. Today she’s shouting that she has a disorder and that she can’t socialize with people so they can’t come to our house & she’s more comfortable to go to theirs. I let her hang out after school with friends, yet today she’s screaming at me that I don’t understand what a disorder is and how it makes her unable to talk to people? But she has lots of guy friends who got her into lots of trouble & she had no problem talking to them. I told her she can sit down and talk to me about it so I understand, but she started screaming about how this is why she never tells me anything. I didn’t yell while we were talking. All I did was suggest her friend sleep here, since we have a guest bed and bath and she has the top half of the house to herself ATM, and when she got mad I told her to sit down and have a conversation with me so I understand what the problem is. I don’t know what I did wrong? via /r/Parenting https://ift.tt/2CA5HSG
