I'm super worried about one of my students. 15 years old girl.

On friday some of her classmates made a (humorous) remark regarding use of drugs, to which I replied is the same humorous way. I tend to deal with these topics this way, making it too serious often kinda closes the communication with tenagers.
But she replied to them in a very harsh way, so I switched my tone, cause I felt it was something that was really hurting her.

Then I remembered that she moved with her mother here (parents are divorced) year and a half ago, and during the weekend I could not help thinking about how it might be related...
So yesterday (monday) after the class, I asked her whether she had a relative with drug issues (it was the brother) and whether it was reason why they moved.
Poor girl started crying, and telling me the whole story.

Abusive father. Beats the wife and the children.
Older brother (not a minor) using drugs, spending all his money, can't keep a job because of it. Father thinks a good beat is the only way to fix it.
Mom divorces and runs away with her (still a minor) but older brother decides to stay.
The girl thinks brother is being stupid, but comfronts her father about the beating. And know what happens? Father threatens to kill her. Damn it, fucking scumbag of a father threated to kill his own daughter, cause he never really wanted her in the first place!!

I've known this girl for a year and a half, she never ever said a word about it.
I already talked to the counselor, and she said she's gonna move everything aside to help the girl, but our resources are so damn limited and there is so little we can do - other than offer support.
Not asking for advice or anything, this is just a rant, but here I am, in front of my computer, crying, cause life is so unfair and I feel so helpless.
Fuck everything.

I hope you lending an attentive ear helped her either to realise she's not alone and to get it off her chest. But I also know some things aren't fixed with professionals, and yet I hope thats not the case here

I'm pretty late to the party. As someone who had an awful childhood, I can vividly remember the few adults who recognized my life problems, said this isn't okay, and tried to help. So, you've already likely made a lasting impact on their psyche.

I'll be a teacher in some months, so stories like this open my mind to two scenarios

1.) When I was small, kids bullied me relentlessly through out k-8 9-13. I kept telling teachers over and over that I was being bullied, and now I realize that even if they wanted to do something, there was very little that I could do.

2.) There were only two or three teachers I really trusted when I was in school. One was my sped teacher, and one was my high school art teacher. I felt like they could hear anything I had to say and I knew I'd be safe with them. Unfortunately, both of those teachers had cancer and died before I graduated.

anyway, in a roundabout way I just want you to know that she felt safe by telling you what she did, and it's more the councilors job to access the situation once you've spoke with her right? The councilor can also call CPS if she feels like its worth investigating but it sounds like she's safe with her mother. I wish kids didn't have to go through situations like these. I have no idea how I'll be an in person teacher, my certification program preps me for online teaching which is how I'd like to teach in public schools.
