There were two schizos on my floor in the ghetto apartment, one man, down the hall, one lady closer by. The man was a convicted child molester that worked at McDonalds and used to dangle himself out of his 5th story window for fun. He once left his chirping smoke alarm on his windowsill for weeks, where the way the building was shaped amplified it for all to hear, until it finally died (astonishingly, he was white.) He also never turned his lights on.
The lady was the angriest woman I have ever seen. She’d menace anyone who happened to be walking down the hall at the same time as her, screaming, threatening, spitting mad with accusations that made no sense. It got to the point where I wouldn’t leave the apartment unless I knew for sure she wasn’t out there. She got on a tear one day and beat the shit out of the old steel mailboxes set into the wall in the lobby with her bare hands and broke most of the doors off. She also somehow retained custody of her 10-ish year old daughter and would scream rant non-stop at the child about how God wasn’t real. She, too, had a vacant apartment next to her. And directly across from her.
What I’m trying to say is, you seem like a genuinely sweet person, but schizophrenia is irrational and terrifying. They will decide you are the enemy for no discernible reason, and they are dangerously unpredictable. She might seem terribly annoying but harmless, but that can turn on a dime if her delusions get into the wrong twist that day. Stay safe, keep documenting/reporting, possibly arm yourself.
Also, if your building is anything like my old one, they might not want to boot her. Fairly certain mine was double dipping and getting money from daddy government and the halfway house that was supposed to be housing them both there instead of a normal apartment.
