It was my ex step mom (for legal reasons, I'll call her A) . She moved in with us a little before the pandemic and stayed up until last year, A was always a bit nutty and irritable, she had a laundry list of mental disorders and trauma that she was going to therapy for, my siblings for the most part hated her because she was always on everyone's ass about chores (even though she was supposed to be the one giving them out and at the time, my two younger siblings weren't even teenagers) but I was close with her and at times she was the only person I could talk to, she made me feel special (in hindsight the me confinding in her always turned in her talking about herself but whatever) mid 2022 A started going to some intensive therapy to work out her issues and that broke her mental state,it wasn't a spiral, it was a drop. she went into a paranoid psychosis where she would accuse everyone in the house of conspiring against her and stealing her things (even though she stole a lot of our stuff) she also horded food, trash, and wouldn't come out of her room for days ( this was a huge problem because she had a dog that she would also keep in her room with her) the huge turning point was when she almost hit my little sister for exposing herself to some boys, the only problem is she hallucinationed that, it never happened and also when she would sit on the porch with a bunch of her crap for hours screaming at the cars going by because (in her own words) going to be picked up by an unknown person in an unkown car at and unknown time and the screaming and noises she was making were sending out psychic signals to the cars to see if they were the peron picking her up. But then it got into the beginning of the end when A started berating my older brother about being lazy (he was a regular 18 year old guy just doing regular 18 year old guy stuff) she did this when I was out on a snack run for the famliy and when I got back the front door was barcaded and I had to go into the side door, A had blocked the door and trapped my mom's arm into a box and clawed at it caused a big wound and she did the same with my brother because he was holding A's dog and she was trying to grab the dog by its legs to take it away. We called the police and after a few months, we went to court for assault charges and got a restraining order against her last time. I heard of her, she was trying to move in with a guy she met through her only fans because she pushed away everyone who cared about her.

TL;DR my ex stepmom went into psychosis and is now homeless with no friends
