I'm a 17 year old girl who's recently entered sixthform and recently got a job so I have a lot of stress anyway, but i guess this irrelevant anyways but it has recently helped me to notice even more about what has going on at home.
My 13 almost 14 year old sister's behaviour is outrageous and has been for a couple of years now. And this behaviour is causing my mum's health to get worse and worse and she is unable to cope with her behaviour.
My sister smokes/vapes and does drugs such as weed, she also drinks and hangs around with the wrong crowd and as much as we try to stop this from happening it is impossible for she simply does not listen. I haven't mentioned this but my mum is techinally a single parent as she has a bf but he can't really do much and my father isn't really in our lives that much he doesn't help at all. 
My sister's behaviour has been getting worse and worse recently she's been stealing from my mum and has been running away and doing things behind her back. She's recently been suspended 3 times in the first 2 weeks of year 9 and has already had the police called once on her as she ran away. 
The arguing is worse though as she will stand there swearing and insulting my mother telling her how bad she is as my mum shouts back in a failed attempt to stop her. And when she puts herself in the way from my sister getting out my sister will get physical and push her out the way etc hurting her. I don't know what to do in these situations multiple thoughts run through my head, some telling me to hurt her for hurting my mum but ik that won't help so I end up collapsing on the floor in tears, she's caused me to have multiple panic attacks and I don't know how to stop them. It's getting to the point I'm scared to come home in case it happens again as i can't bare to see my mum cry and become even more Ill...I'm genuinely scared I might just lose her and I don't want that.
We need help we really do and i know she can't do this on her own and so I'm trying to help but I feel useless and I just need some advice on what to do. 

I don't know if this is the right place to say all of this but if you've read all of this thank you.

I do so feel for you and your mum. It sounds such a tough time for you. I'm a mum with two girls and one has suffered from her sister being very difficult and quite abusive to me - she has mental health problems. Have you contacted the Mix which is aimed at young people and may be able to help you? you can call and do online chats with them, or I think you can call family lives, do you have someone at school you can talk to ? a counsellor who can help you as it must be so tough for you, and they may know more how you can help your mum and sister. Take care of yourself. 
Hi, I understand that this is a very troubling and upsetting situation. Perhaps you could get social services involved, they're not simply there to take children from homes, they're there to support families in difficult situations. You can read about them in our articles here. You call them through your local council, who will put you through. For yourself, you can talk to The Mix, they're an organisation that helps young people in difficult situations, you can call them on 0808 808 4994. Take some time for yourself, although it might seem selfish it helps get you in better place to be able to help your mother. Have you spoken with your mother about what she might want to do, how to deal with your sister? I know it might be a stressful and upsetting to discuss, but it might to talk together. If you feel you need further support please e-mail us at or call our freephone helpline on 0808 800 2222.
