She has always disliked me. My big sister can do no wrong but i can never be good enough,even when i fulfill her every whim. She is horrible to me,putting me down,undermining me,dismissing any probs i have as just so unimportant. She is a narcissistic mother. But why do i have to be her pet hate? I am always kind to her.I give her no grounds to hate me.Yet she does.
