Sorry about this being so long.
I'll start out with the basic information. My parents have been married for 17 years. I have a younger brother. We have legal custody of my 2 cousins (Emily is 6 and Alisia is 8). Our house is far too small for 6 people and 3 dogs. Me and my brother have our own rooms (my parents refuse to let us share a room). My cousins sleep in my parents bedroom. My parents sleep in the living room. My mom works 8AM-6PM and my dad is disabled.

A normal day at my house during the school year:
Go to school (7AM-4PM). When I get home my dad is either sleeping in the living room or screaming at my cousins for some little thing. (I got home once to hear him screaming at Alisia for 'following' him around the house!). I do my homework. I have to make sure my cousins have their room clean and then help make dinner. My brother, at this point, is on the computer playing games. When we get done with dinner, my mom gets home. We eat dinner, the whole time my dad is making fun of us, then I have to clean the kitchen. If I don't clean it my parents will fight for days about which one of them should havs cleaned it. I run and hide in my room for the night. My parents stay in the living room; fighting. They scream so loud I worry that the police might get called to my house. I hear doors slam and screaming all night! I cry myself to sleep on most nights.
A normal day at my house when we don't go to school:
I get up around 11AM because my cousins are being loud (thier room is next to mine). My dad comes in my room about that time to tell me to wake up. When I get out of bed I find that my brother is on the computer playing games. I get me something to eat and sit in the living room (I get screamed at if I go in my room ). About 30 minutes later my dad is asleep again (I usually sneak to my room then). I have to fix my cousins a lunch around 12. My dad wakes up after that. He then starts screaming that my cousins need to stop eating every hour or something else that makes no sense. I hide in my room after lunch, only to hear him saying "She needs to get her lazy *** out of her f***ing room!". I try to avoid my dad as much as possible until dinner. Between lunch and dinner; my brother is playing on the computer, my dad is screaming about something or sleeping, and my cousins are trying to find something to do. When it's time to make dinner, I go and help. My brother is still on the computer, but my dad says "he (my brother) helped me all day. Unlike her (me). She stayed in her room all f***ing day!" When we finish making dinner my mom gets home. After we eat, my parents start fighting about something stupid. I go in my room untill everyone goes to bed (around 1AM because my brother stays on the computer all day). Then I leave my room to get something out of the kitchen, I don't sleep well if I don't eat/drink something before bed).

I don't know what to day anymore!! My parents fight at least once a day. I mean there are holes in the walls were my dad threw things at my mom! My mom is wanting to leave, she just can't afford an apartment on her own. My mom says my dad is being emotionaly abusive (I think so too). My brother acts like he's not in the family anymore. I'm trying to get out of the house as much as possible (thank God for my friends!). Now my cousins, who have been through enough in thier lives, have to go through this!!
I'm moving out as soon as I'm 18, so I hardly care anymore (16 years of this is more than enough!). I still want to try and help my 'family' a little, so my cousins can live in a more stable home.
Can someone please help?!
