This is a serious and urgent question... please help me.?

okay so i have this problem. i am 14 and i havent been happy for months now. i dont think im depressed but im not really sure. i dont like getting up everyday and going to school or dance cl. now i just think of school and dance as a way of getting away from home. you see my parents fight every single day and its really beginning to affect me. they scream back and forth at each other about money and bills and EVERYTHING possible to fight about. every other word out of their mouths are curse words. i have 3 other siblings who are younger than i am and my parents involve all of us in the arguements that they have. they scream and curse at us everyday and its really hurting me and making me feel like its partly my fault. my siblings dont really understand what they are fighting about but i do. my mom has called her parents to talk about my dad and she has also called my dads parents and complained to them. my dad hurts my brothers all the time. i cant say its child abuse but he definatly is hurting them. and if i am the slightest bit upset when im home they will yell at me telling me to drop my attitude. they dont think to ask whats wrong or if they can help. i feel like no one understands. i tried talking to my friend about it but she is trying to make her situation sound worse than mine and shes not really helping. i just cant stand living like this anymore. please dont tell me to talk to my school guidance counselor because i did and it didnt help. everyone in school is always asking me if im okay and i just tell them that i am because i dont think they will understand and i dont exactly want my personal buisness going around school. my teachers are always asking me if im okay and i just say yes because if i dont theyll send me to guidence. i go to school everyday and fake a smile and a laugh just to get by. the slightest things that someone says can make me feel like crying and sometimes i do cry. i am just waiting everyday for my parents to tell me they r getting a divorce. my dad tells me everyday whether he is mad at my mom at the moment or not that if i grow up and act like my mom he wont talk to me and that he wil be very disapointed. he says all the time that he hates my mom. my parents havent slept in the same bedroom for 9 years now. i dont know what to do anymore but i need help.
