family relationships..., problems... Options

[aud_chua]

(i didn't really know where to put this... but it's a kind of "relationship" problem, right???)

this has been bothering me for a really long time already....
just wanted to see if anyone can help me out here...

your mother wants to be that "caring" person she's supposed to be. as a result, she invades too much of your private space. then, she also wants to "help" you with your school work. she ends up being demanding. one more thing, she calls her wild mood-swings and yelling as "lessons."
i truly love my mother but she makes it so hard to understand. yelling every single day, and telling me that i'm not good enough... that doesn't seem like a good mom. i mean.. just the other day, i told her that my school's mock trial team didn't advance to the state finals. guess what she said. "you're team is just not good enough. accept it." she could have said something more comforting..

aside from my aggravating mother, i have these two elder sisters. aside from being older than me, nothing else makes them what they are. i mean.. they depend on me for so many things. both of them act so immaturely, it's not funny. one of them always asks for help with her homework and term papers. while i stay at home and do it for her, she goes out and party with her boyfriend. when i do tell her to do her work by herself, she counters me. "what kind of a sister are you?!?! why won't you help me!??!" that's what she'd say. and i'd try to explain that she has to be independent and learn things on her own. later, she'll tell me "you have to help me now!! i'll do my work next time!" but she never does... the other one is always acting like a child, i have to watch over her every second when i'm out with her. in some aspects, she's mature, i.e. holding a job. but other than that, her attitude is like a child. she throws tantrums easily. then she looks at cartoons all the time and tries to emmulate them. also, some of her actions are not proper. i try to correct her but she makes it impossible. she tells me, "i was born this way! there's nothing you can do..!"
i only have so much patience and endurance in this body. there comes a point when i just want to scream at them. but then, they're my older sisters, my kin.. i don't want to seem like i'm being mean..

so my question is...
what should i do?? should i be indifferent to my feelings or tell them? should i ignore them? or something...

tnx very much for taking the time to read this! ^_^

All I gotta says is....I'm glad my parents are computer illiterate and that I only have one younger sister who's just as smart or maybe even smarter than me.
