Sorry it has to be that way. I once lived with three guys in a two bedroom house and worked six days a week. Even had to clean toilets once in a while. It's called paying your dues and it leads to bigger and better things. Not saying it's right about your living situation, but you can always take Skyhighs advice and quit now while you're still ahead.
All I can say is.....glad I didn't quit when the chips were down......
