You don't hate them! You just think you do....my friend has the same kind of problem! She really takes it out on her friends mostly me! She physically and verbally abuses me, of course I defend myself which has caused a few fist fights. Next time she hits me bye bye friendship, I'm not putting up with her anymore, especially since she hits me in public, that really made me make up my mind, the problem is my BFF is friends with her and I always wanna hang out with my BFF(who luckily is kinda holding a bit of a grudge too, by High School she'll be in her own little freak group!MUEHEHEHEHE) anyways waaaaaaaaaaaaaay off topic! Maybe you should talk to them, usually at that "time" of month girls/women turn evil! My mom has been horrible lately and it's driving me insane, picking at me for everything, I just tell her to stop nagging at me and I go somewhere FAAR away(a walk,out to see my bunnies,ect.)! Calling friends and pets really help, keep a diary too(me and my BFF plan on stealing my "friends" little diary, we truely wanna know what she thinks of us!)....Anyyways give them a talk, it's not going to hurt, I understand most people don't like talking to their mom's about anything but if your not close try to get close to her. And for the sister well sisters(ESPECIALLY older sisters are the biggest pains in the ass,scuse my language) I have an older sister who used to bully the crap outta me and always hit me, but now she's practically afraid of me, hehehehe! I showed her what I was made of and she knows if she messes with me she's in for it....HINT: joing a wrestling team really helps for older sisters and abusive friends! Just tell your sister how rude she is, video tape her being mean to you, then show her it, she'll how rediculous she really is! Anyways good luck with the family! I hope this info helps!
