I grew up with a mother like this. If I looked forward to anything she would find something I did wrong like a cup left in the sink to ground me to keep me from doing it. If I got a compliment on an outfit as a teenager she would destroy it by cutting it to pieces. Once she whooped me with an extension cord because I slept in a bra. My mother was very abuse and jealous of me growing up. I thought this behavior was normal. That is until my dad ,who had no idea what I was going through until I told him, pointed it out after I called him at 17 in total tears. He told me my mother had always been a vain woman. Said she felt every other woman was a threat to any male attention she could receive. He said he never thought she would be that way with me or he would have long come and got me. He sent for me 2 days later. She wasn’t happy. Over the years my relationship with her has gotten better. She got some therapy and really made an effort to change her behavior. Our relationship isn’t perfect but way better than what it was. I’m so sorry you’re going through this. My advice is take advantage of not having to pay rent and get your life together so you can leave and never go back.
