If definitely sounds like a toxic relationship. It is hard when you are in that environment. You just have to keep reminding yourself that it is THEIR problem and not yours, nothing you do will ever be good enough for them because they are the ones who have the issue. If moving out isn't an option for now. Just do your chores the best you can, if they yell and scream, pretend to take it but deep inside protect yourself and say "you can't touch me, you have no power over me". When I was a teen at home in an abusive environment I coped by staying out of the house as much as possible during the day, and I did whatever they asked me to, didn't argue or fuel into the fight or fire, and just kind of bided my time. I just kept telling myself, I am going to get out of here, I am not going to be here forever. It will get better. Take care of yourself Ok.
