Neighbor Bangs On Our Shared Walls At Every Hour Of The Night, And Claims She Does So Deliberately To Harass Another, Third Party. Police, Landlord, Social Services Have Not Helped. What Are My Next Steps? [new York City]

My neighbor is an older woman who bangs on her floor and walls every single day with a hammer and other instruments, usually concentrated in the late evening but routinely continuing through 3 AM onwards through sunrise. As of today, she has been banging on her wall from around 3 AM until noon.

I have spoken to her, and she claims she does this, bangs on her wall, because she believes her upstairs neighbors are running a business in their apartment and playing music- you would think she'd hit the ceiling, but she never does. I have been in the hallways, and she has even invited me into her house on multiple occasions, and I have heard none of this noise she claims. I have spoken to her upstairs neighbors, and they say that she has been harassing them for years, and they obviously are just a regular couple living in a regular, new york city apartment.

I and the other neighbors have asked the landlord for help in the past, with no resolution. I have been told by the landlord to call the police, and I have. The police have literally bounced back my noise complaints and told me this is the duty of my landlord to resolve. I have called 911 wellness checks on her multiple times, with no resolution. I have called my city's adult protective services on her, and recently received a letter in the mail that she is ineligible for assistance.

As far as I am aware, legally and medically she is of sound mind. She has told me, to my face, that she does this willfully and deliberately to harass others, and yet I am bearing the consequences and losing sleep over the matter. I have anxiety, and this has exacerbated my condition and contributed to panic attacks.

Is my next step to sue the individual? Can I get a protection order? Should I speak to the police or a lawyer first? Would this be civil or criminal? Am I due damages because of my lost sleep and stress?
