I Feel Genuinely Scared For My Life Living In My Apartment And Won’t Go Back Now.

I’m a 23 year old female living alone in Florida. For the past year, my upstairs neighbor has been extremely loud.. for a while I didn’t complain and it stayed the same. One day I heard a lot a lot of noise coming from up there so I told management. Since then I have dealt with purposeful stomping (there is videos on my Reddit page) and genuinely feeling like they are harassing me and angry at me. Last night, I heard them beating their dog. I couldn’t do it and I had to call the cops but now I’m genuinely terrified to live in my apartment because what if they try to break down my door and kill me. If just complaining to management made them that mad, what is telling the cops gonna do?? My brain cannot tell myself I’m going to be okay sleeping alone in that apartment and that I need to barricade my door to sleep in there. I’m so afraid for my life and have no idea what to do. Their dog was crying over 10 minutes wailing and screaming while I was waiting for the cops. Like genuinely all I can think about is him standing at my door and my only way out is to jump off the balcony. I’m terrified.
