Why does she hates me?

I always asked myself why does she hates me so much? I really dunno what i did wrong.. If anything happened i am the one she will blame. In fact she has everything she got education, good job, can drive got bf. But i dont. I had to work when i was only 18. i also want to enjoy my life but i never complaint or be jealous of her... But why when there is an argument i am always in the picture. I am hurt by her words. Always accusing me of things which is not true. BUt what i go through is nothing compared to what my parents when thru. I really hope that she will realise her mistakes and realise that we care abt her. Please God help me make us a stronger person. I want to have a happy family. Please. :(
