Is there a way I can go away with this family? I am 12 and at school life is hell because I'm not christian. I have a 19 years old sister who has never loved me or showed me affection. Since I was 6 she together with her friends bullied me and told me bad thigs like, spoiled little cruel child, and they laughed when I cried. I always told my mom but she pretends nothing happened or said well you are the youngest child it's normal she says so, you are spoiled she's right. Another time when I was playing with a neighbor boy of her age she told him 'don't let her win, she is a spoiled little b**** and you will spoil her even more'. I always cry after she says such things. I am a quiet child who just wants love she always treats me bad. Then mom shouts at me for causing problems in the family. They don't care if I cry the whole day in my room and drag me by the arm even if I don't want to eat. I hate them all I want to run away. It's always my fault. My mom can't understand me or comfort me for the life of her.
