Family Time

So this was my morning, I got up went downstairs for breakfast, made my toast, then for some reason my sister pushed me into a cupboard and hit me, then when I went to get a plate she hit me twice on the back again and after that my mum blocked the toaster so I couldn't get my toast then she pulled my hair until I screamed in pain, let me get my toast, however she then continued with abusing me calling me fat, a whore and bitch, then she decided to hit me and pull my hair again and tell me what a horrible child I was and she wishes I wasn't hers then she said I had to get out of her sight and I also can't have food from this house now, all while my sister sat and watched, doing nothing to help even though she was the one that hit me, yet she was happy for my mum to abuse me and blame me even when I did nothing. What kind of sister is that? What kind of mother is that? better yet What kind of person does this to their child?
