Any Ideas For This Target of A Bully?

I am going through the same thing. I am college student who is saving up to move out who lives eith a disabled parent in apartment complex. The neighbors above us are rude young college kids. The toture started when we said something to the office about them entarining to ludly and arguing before that it was quiet. All of a sudden they started slamming doors hard and throwing objects down that sounded like heavy furniture all hours of the night and blasting music from 9am to 4am. The area targeted is mt room there room is above my room constantly I loud music is bouncing at 1 and 3 am. Everytime I enter the bathroom someone starts slaming cabnients and each time at 4 in the morning someone starts making a banging or tapping noise usually in the bathroom area or by the closet. Because alot of times my mother is sleep she gets mad at me because I am help trying to find solution or venting. I get blamed and because this happens when she is sleep or not by her room but sge has witnessed inicidence she feels I am being to sensitive. I feel uncomfortable in the place and feel dread in reentering. We have notifiedf the rental management but they just give us the run around. The cops will probably be no help because the neighbors are able to but on front and con people by there all american appearance. Things have gotten so bad that it is causing disention in my house my mother doesn't really want hear about the situation and I feel like no one truly believes this is happening. I feel nervous and have anxiety when I return to the residence. I have ocd I feel that they are doing this partly because of I might do things differently and they think it us fun to target me. She tells other families that I am just being sensitive and they start fussing at me. I am looking for suggestions.
