traumatized eden tenant

This place is Okay. the problem is some people who rent here. I currently stay here and there are 8 or 7 people occupying the flat above me. they are constantly saying bad things to me so as to provoke me to anger. I believe it's bitterness, hate or jealousy and we don't know each other like that. They have issues when I cook, eat( to the point that they open their toilet door to release odor over the balcony so as to irritate me), my car, the fact that I stay alone... things that are non of their business. they went as far as threatening me with witchcraft as well as cursing me to be fired at work. It has been like this since I moved here, had hoped they would get tired but they keep on getting worse. they are making my stay horrible. I mostly work from home and have picked up 3 voices who do nothing but to provoke most everyday. I've threatened to report them but I end up feeling like I'm talking to 3 year olds. they sometimes throw dirty water over the balcony, staining my curtains. they are very rude, it's nothing when you hear them in just a month but in the long run it feels like a burden. I mean, this is a place where I'm supposed to wind and rest my mind whenever I'm troubled out there.
