Hey Rei,

If you have tried everything to make the situation better and she still won’t make attempts to be nice to you then ignore her. Just live your life and she can live hers. I know that’s harsh and I know you want the situation to be better but if she’s not trying then you’d be better off just ignoring her. Live your life. Go out with friends and keep positive people around you. People that will make you feel better about yourself and not people that will put you down. Rei life is going to throw curve balls at you and believe me I’ve dodged a few in my life myself. But don’t let your sister treat you like that. Just ignore her and maybe one day she will get the picture and be like “damn I shouldn’t have treated her that way” and try to make things right. Sounds like you have tried to make things right but it’s like beating  dead horse, waste of time!

Hope this gives you some inspiration!
