Hi, I have sis, a really bad person. My parents spent big amount of money to get her abroad for nothing. everyday she sleeps late night or early morning and woke up afternoon or night because she's playing game or chatting with her online friends. She always said she's in bad mood, don't wanna work, dont wanna help with dishes, dont wanna study, dont wanna stop playing, if we call her need more than 5 min for her show up. Even tho my parents really care for her, she said they are noisy. Im sick with her, what should I do?

Move out when you can I guess.

I was just like your sister! shes having a hard time, mentally. Maybe its mental illness! perhaps depression from the pressure the parents put on her. They mean well, sure! But in her head its too much!!!! this will change over time! not fast enough I know, but dont lose hope!

I have a twin sister and we've been together all our lives. She has had stretches where she has been absolutely unbearable and selfish, but through it all she always had a reason. She was frustrated with something happening to her, she was frustrated with how others were treating her. I started to understand her more and realized my own faults. With the lack of context it's hard to give you any proper advice but just try to understand why your sister might be acting that way.
