Hate only hurts you. You can't do anything about your sister, and in fact you may find people who hate you in the years to come and there won't be anything you can do about that either. But you can do something about why you hate. If you only hate because someone hates you, what do you get out of that besides needless stress? Just ignore/avoid your sister, as much as you can, make your own way in life. You could spend a lifetime trying to make someone like you and maybe it'll work, but why should you do all this work and stress and they still might just hate you and in fact enjoy the work you're putting in to make it work. Just walk away and live your life. You're better than this.
