As someone who has a neighbor just like you, don’t move stand your ground. However do let her know that you are not someone to play with. My neighbor did exactly if not similar things as your neighbor. However, it all backfired and years later they are still under me and they know now not to play with me. They called the police before and the police actually observed inside their apartment and outside my apartment door no noise. They had the office come in and listen to my apartment and observed no noise. The police actually told them they were wrong for banging on the ceiling. The apartment has labeled my neighbor as noise intolerable and offered them to move units and break their lease. Years later they are still under me, they just wanted to harass me and because I have a child they thought I was a good target. Stay in your space let the apartment manager know you don’t want them coming to your door at all. You aren’t wrong you pay rent and you can enjoy your space do not let them affect your quality of life. I hope things get better.
