<human>: Can you give me a shortened version of the text?

My parents haven't gotten along in a long time. Can't remember the last time they slept in the same room together. I have a twin brother who moved out last year; I moved out last August but moved back because I am a grad student. I make $500/month through a university job that pays my tuition and keeps me busy enough (along with classes at night) that I don't have time to get another job to make more money for my own place.

Dad has alcohol issues. Works 9 days in a row, has 2 days off, works 9 more days, etc. and when he has days off, all he wants to do is spend them at the bar and come home and be a drunk asshole to all of us. Mom doesn't do anything about it and lets it happen. Ends up being miserable for the two of us while he's oblivious. 

They both bitch about each other to me. My dad gets pissed off any time my mom asks him to do something. Ex) Our laundry room/bathroom just flooded and we are ripping the carpet out to put new flooring in. Mom asks dad to help her and all he does is yell that he has to do everything. The only thing my dad does at our house is literally mowing the grass. My mom and I do all the cleaning, cooking, bills, etc. Meanwhile, mom will complain about dad being an asshole, how he makes her miserable, etc.

I seriously can't take it. I'm tired of being the one that they complain to about the other. I basically just hang out in my room all day or try to avoid going into the same rooms as them because it always ends up being a fight. I wish I could move out so badly, but I don't have the funds. There isn't anyone around that I could even move in with, and my boyfriend lives 2 hours away and that would prevent me from being able to go to school. Just looking for advice.
<bot>: Parents fight constantly and I spend the majority of my time avoiding them. No money to move out. What do I do?
