Hi there
Thank you for your message; it really is a good idea to get some advice when things are difficult and from your message it does seem like you could do with some support at the moment. You said that you feel that everyone in your family hates you; it must be really difficult for you to feel this. It's understandable that you feel sad and hurt as you are being hurt physical by both you cousin and your mum, being called names by your mum and having to deal with your aunts drinking and feeling your nan blames everything on you.
No one should physically hurt you like this and it's really important that you know that you have a right to feel safe and protected at home and be to supported with concerns about your aunt and nan and how they are towards you. Young people often find it really does help to talk to a trusted adult in their life, to get some support with being safe from being physically abused and hurt at home. This adult could be someone in your family, an adult friend, a teacher, school nurse or counsellor, a social worker, your doctor. It might help to have a look about what other young people have to say about being physically hurt at home on the ChildLine message board or have a look at the information in Explore on physical abuse. It might help for you to find out you are not alone and that with the right kind of support things can change for you.
It could also help you to remember that this is not your fault. Try to focus on the positive things about you that are true to help you get through this. Remember your strengths, your talents and the qualities you have that make you who you are that help you to stay strong and positive.
It must be really difficult for you feel you have no one to talk to, you deserve to have someone listened to you. Please come and talk anytime to a ChildLine counsellor. They won't judge you; they will listen to you to get the support you need.
Take care
Sam
