I cooked dinner for my mother and set up my pc so she could watch the tennis.She then screamed abuse at me all day said she cant handle my voice and stop shouting even though I wasnt even speaking . My sister is drunk and screaming all day .We were supposed to go out tonight but shes drunk and very abusive and when I said I wasnt going with her she started screaming more abuse at me said I was the one with the problem . I think they did this so I couldnt go tonight . Theres a festival on and for the last three years I missed it over my sister and her drinking . The nicer I am to my mother the worse she treats me.Yet she dotes on my sister who is a psycho and violent. They never ask me how I am even though Im seriously ill . My father agrees with my mother no matter how wrong she is. Im the one whos shouted at by everyone.Im abused day after day . I dont know how long I can take it .
