New 70 yr old roommate - condition is not what I was told it was. Now I have a huge problem and need help.

I had a room for rent. I saw a post on FB there was a 70 YOF looking for a room to rent. I had one, so I contacted the poster. The poster was a nurse aide for roommate ("S"). The nurse aide said "S" was independent, took care of herself, used the bathroom on her own and used pull-ups for "just in case she didn't make it), feeds herself, washes and dresses herself, etc. "She uses a walker but other than that, all good."

My new roommate "S" has been here 3 weeks. She has physically been in the bathroom 2 times to shower. She has been laying in bed, wetting and pooping in the bed. Filling diapers and dropping them in a bucket next to the bed or on the floor next to the bed. Her nurse aide comes M-F between 9 am. and 3p.m. to help with more challenging things, like laundry, shopping, cleaning. I have not seen the nurse aid take soap and water into her room to bathe her and she has only been in the shower twice. She has half of one kidney and drinks tall cans of Long Island Iced tea every day. She chain smokes cigarettes and smokes weed. She stays in the bed, drinking, smoking, laying in her waste and next to her waste. She opens the windows and leaves them open with temperatures ranging from 30-50 f outside. My heat is running non-stop. The ammonia odor is so strong, I got sores in my nose and it set off the carbon monoxide and explosive gas detector in the kitchen. My washer and dryer wreak of ammonia and poop. At most, she has 30 hours per week with an aide. The other 138 hours per week, she is on her own and not performing any self care other than feeding herself long island ice tea, smoking cigarettes and weed. She is choosing to stay in the bed laying in her waste and with her waste laying around her in balled up blankets on the floor and a short open trash can. I couldn't take the odor anymore and started knocking on the door and pulling her trash out of her room but it is very hard to do with the smell as strong as it is. (She has half of one kidney on top of this.) If her nurse aid doesn't come that day she doesn't eat or drink anything besides the long island ice tea, and she doesn't clean her body or clean up her waste. I had a talk with her because I know she CAN get up and use the bathroom and clean herself up (per her nurse aid) but she chooses not to. I told her I could not allow what is happening here continue. By definition, if she is unable to perform the basics of self care, she needs assistance 24/7. She is harming herself but she is also harming me. I have spent a fortune on odor absorbers, candles, odor blocking detergents, etc. And now my electric bill is going through the roof. I'm freezing to death and can't breathe in my own home. I ran her blankets through the washer for 5 hours, washing over and over and using baking soda and vinegar and odor blocking detergent and still couldn't get the odor out. One blanket was full of burn holes. What can I do? I can't live like this and I can't become her 24/7 caretaker. I caught the windows in her room still open in the middle of the night with her sleeping next to the window with it 38 degrees outside and my heat running non-stop. Her behavior is putting both our health and safety at great risk. When she has a doctor appt, she straightens right up, acts competent, and her aide is right there with her. She comes back here and reverts back to bedridden drinking, smoking, filth, windows open, no self care or bathing, and laying with filth. What course of action can I take to get her the care she needs and to protect my own health and safety? I'm in my 50's. I can't live in waste and cold. I have 2 jobs and my own health problems, I can't be her caretaker at the level she needs.
