Sorry to hear about the rough housing situation, @Deborah813. It sounds like you have the misfortune of very inconsiderate neighbors. I think you have the right idea of seeking out spells for protection, cleansing, and positivity- try not to let the mess and noise of others bring you down!
If you find yourself to be in an unsafe situation, I agree that it’s probably time to look for other arrangements if you can. Your safety comes first! It is good that you have brought the matter to the attention of the manager, a lawyer, and the police- they’ll have everything on record, which will be good support if your other neighbors start to file complaints too.
I’m sending you good thoughts and all the best of wishes- I hope the situation deescalates or you can move to a better place! In the meantime, keep drawing positivity to yourself and practice self-care too (perhaps with a self-care bag or herbs)! 
Blessed Be!
