Husband's estranged aunt living with us

Hi ladies!

My husband and I have an 18 month old and I am currently 17 weeks pregnant with our 2nd child. I have been extremely stressed out with working from home, caring for our son, keeping up with our home/cooking, and dealing with my husband's unappreciative, fake, and disrespectful aunt who has been living with us since April of 2020. Although she has never been in my husband's life, I whole heartedlty accepted her into our home because I felt sorry for her. She is a breast cancer survivor, and does not have immediate family who live in the US (all of her children are in Europe). Long story short she can no longer work, does not have Medicare benefits so she can't afford to live on her own or go to a nursing home or AL which is why she had to move in with us to avoid becoming homeless. The last person she lived with no longer wanted her because of her nasty attitude and she started to show signs of dementia and she didn't want to be responsible for her. She wandered and got lost one day and her friend reported her missing, the cops found her on the streets after 2 days and called my husband to inform him that they found his aunt and she couldn't go back to where she lived before. My husband instantly drove an hour away (at 1 AM) to pick her up and bring her to our house as I cleaned and prepared a room for her and made sure she had a meal when she arrived. It was ok in the beginning and I made her feel welcomed and would cook for her and bring her meals to her room since it was the height of COVID so she had to quarantine for 2 weeks. After all that passed I showed her around the house and where everything in the Kitchen was and told her that this was her home now and she could eat, cook, drink whatever she wanted and to let us know if anything was missing that she needed. I also bought her a new wardrobe and offered to take her to a hair salon to boost her confidence. Well I STILL have to cook and bring her meals to her room like its a hotel w/ RS (because she doesn't like eating with people), wash her clothes, and do other things for her because she doesn't feel "comfortable" doing it herself since it's not "really" her house yet she makes coffee twice a day since she loves it so much. She also has the nerve to tell ppl that she "fears" us so thats why she doesn't make food on her own and waits for me to do it for her, she tells ppl we try to control her because we ask her not to walk too far if she's going on walks so she doesn't get lost and come into contact with COVID positive ppl and infect us. My husband has had to go pick her up at random places because she said she went for a walk in the neighborhood and got lost (she really goes to play lotto or buy things and hides it from us). She gets nasty attitudes when she sees me washing dishes or vacuuming and I tell her its ok, I got it when she asks to take over, and she has called me out of my name to my face in several occasions and denies it when I confront her (trying to play into her dementia which I think she fakes). She has also called my husband's 8 yr old neice nasty names under her breath when she spends the night with us but speaks highly of her when her parents come over (FAKE). She is a bad person overall and I learned that she has always been this way. Her children want nothing to do with her because she left them when they were younger to go have "fun" with different men without the distraction of being a mother to her children. She has made a lot of horrible life choices and acts as if my husband and I are the root of her problems instead of appreciating us for being there for her when no one else wants her. I'm fed up at this point and feel my mental health is declining because of her and I fear that something could happen to my baby because I get soooo angry almost every day. I want to kick her out but she would be on the streets and my in-laws would blame me if anything happened to her...she also doesn't have legal status so we can't just ship her to her children overseas....What should I do? HELP!
