how do i deal with a next door neighbor that has really bad psych issues?

not sure what her problem is, i think she could have something like schizophrenia, my sister had it and she had a case manager seeing her all the time, my neighbor has one, i heard she had a bubble on her brain and ive heard her cough a lot like shes throwing up too, made me wonder if she had a brain tumor and was on chemo, i cant ask her cause i cant talk to her, she gets really mean, curses at me when she sees me , or does other weird stuff, yesterday i was just coming back to my apt, she opened her door and saw me and slammed it really hard, made me feel so bad that she was so mad cause i was in the hallway. i tried to tell my apt manager about it but he acts like the door got slammed cause of the wind, i know it wasnt cause i saw her when she saw me and the door slammed really hard, its unfair cause a couple of times someone on my floor slammed the door and she called the cops on me and one of my neighbors for it when we didnt even do it. so i had to talk to a police officer twice for something i didnt do, so why was it okay for her to do it but not any of us? she can get really mean, she dont even know where her daughters are cause they wont contact her cause of the way she is. i heard her kids got taken away from her, so she was probably abusive with them, shes right next door to me too, ive wanted to move but cant find a place, wish she would move, noone takes me seriously when i complain about it, anyways to get her out of here, heard she pulled a knife on someone in another bulding, how do i deal with someone like that when i cant find a place, its not the money, its all the waiting lists for places, ive wanted to move back to syr ny but i cant get a place there either, thought of renting a room from someone, i have income, just cant find something, any suggestions?
