Caretaker is invading my privacy!

At the end of April, 2010 I inquired about an apartment for me and my 2 children as me and their father were seperating. As I walked through the final available apartment the caretaker said, "This apartment is right next to mine, not many people like to live next to me" I didnt at the time understand why, she seemed to be very nice. If only I knew then what I know now, I would have never moved into this building if someone paid me to. Hard to even begin to describe this woman and everything she has done to make me feel uncomfortable in my apartment. She is famous for Post-It notes, she puts them on peoples doors for every issue she has, doesn’t matter what it is, private or not, she puts it on the door for anyone to walk passed and read. First one put on my door said "Danielle, I am sorry about the loud mouth in Apt #202, she will be moving soon" Apartment 202 is right next to mine…so the lady in 202 could have at any time walked passed my door and read this. I also get them when she wants to complain about me talking about late rent, car parked slightly too close to the line in the parking space, my baby was sick and cried alot one night and she asked me to move my daughters crib, my son got locked outside (security building) and she complained about that, asked me not to have my blinds raised unevenly, told me I can’t sit on the steps outside because her exact words "We are not in Harlem, it looks ghetto and trashy". She once told my son (who at the time was 7) "pull up your pants you look like a wigger" I have MAYBE had 10 different friends and family members over in the year I have lived here and she has made a comment or many about each and every one of them and found something to complain or nag about. The worst one is my childrens father, he does not have the greatest passed and I’m not sure how she found any of the information out but she knows way more about him then she should. She is now on this mission to call the police everytime he comes over just to report he is here. There is NOT a no tresspassing order, there is NOT a no contact order, He has done nothing wrong here, has always been very respectful, quiet and comes to stay over maybe once a week to spend time with the kids as his housing is not suitable for them to visit. He is staying with a friend. One morning after he had slept over I went outside, he was still in bed and my daughter started crying when I went outside, the caretaker Robin walked into my apartment without knocking, no notice at all, took my naked daughter into her apartment. When I came back inside maybe 2 or 3 minutes later…she had no reason behind it. She then went onto complain about how late it was when my childrens father arrived. She has cameras in every entryway to the building and seriously must scroll the whole thing because she now knows everytime anyone comes and goes from the building into any apartment. One time a tenant was on vacation for 3 weeks in New York and as I was leaving she says come here, she unlocked the tenants apartment and said, look how disgusting her apartment is! This lady has no limit to anyones privacy, she knows conversations I have had that the only way she could possibly know is if she was listening to my wall. I have many times wondered if she has cameras set up in apartments bacause she knows everything about everyone and gossips about everyone! She sat at her garden one day talking right outside my window telling the tenant outside that I am on a rental assistance program through a domestic violence shelter and still allow my children to see there father and should have the assistance taken away. She also went into detail about confidential information that should not be shared with anyone! I dont know what to do about this situation, I feel uncomfortable in my own home, everytime I leave my apartment she is creeping outside my door, I feel stalked and invaded. I want to move out but I lost my job last month and I am behind on rent. We have made a payment arrangement and if I break the arrangement she will file an unlawful detainer which I cannot have on my record. As a single mother with little money and no where else to go, I feel stuck! What do I do? Do I have any rights when it comes to these things?
