What help can I get if I moved into a house that is unsanitary and overcrowded but I can't afford to move?

My boyfriend and I found a room for rent on Craigslist and we moved in, and then another couple moved in and another person. Before we knew it there were 8 people living in a 4 bedroom house with one bathroom. The landlady is a disgusting pig. When there is someone in the bathroom, if she has to go, she makes her way to the backyard and uses a bucket for both #1 and #2. There are no fire alarms in the house and twice I have woken up to a smoke filled house because my landlady was too drunk and left the house while she was cooking something. The electrical is all wired to one breaker. If I have my air conditioner on in my room and someone turns on a drier every light and appliance in the entire house go out. My roommates are all drunks and the house is always a disgusting mess. I need to get out of here. Are there any kind of resources that can help me get into a different place cheaply.
