Okay well my mum's been drinking pretty much all of my life. I can only remember about 5 days in my life where she wasn't completely smashed. When I was younger she was getting quite violent towards me and my dad. I remember sitting on the stairs when I was about 7, having to listen to her covering him in boiling oil and throwing pots and pans etc. at him, all because he suggested she stopped drinking. Another incident when i was about 10 - she threw me into a wall telling me she might as well go kill herself because i've ruined her life and she wishes i'd never been born, smashing plates over my head, and things like that. My dad is constantly walking out when things get bad and leaving me with my mum but he's normally back by the next day and the whole thing starts again. She's not so much physically abusive now (i'm 16) but she can be quite heavy handed like the other day my brother refused to go to his room when she told him to so she started yelling at him and dragged him up the stairs by his shirt collar. She still says things to my little sister like "oh you're not worth my time", "you can't do anything right can you" or "why can't you be better". She drank a lot while pregnant - one of my brothers is autistic and my sister was born with a deformed heart because of it. My parents are always arguing. Every single one of my brothers and sisters (theres 7 of us) are quite violent and always yelling because thats all we've ever known.
If the physical stuff hasn't happend in about 7 years and i don't have any evidence for like verbal stuff, what can i do about it. My mum won't get help for herself and is refusing to listen to anyone who tries to help her. My dad's so stuburn that he's refusing to do anything about it. What do I do?
