So sorry to hear about your neighbour. I moved out 3 weeks ago because of similar circumstances after my DH nearly got into fight with neighbour over noise.
I feared so much going crazy locked in with their noise we found somewhere to rent at very short notice.
Please send your neighbour a letter explaining the distress their noise is causing you and how its affecting your health?
Is there anyway you can go to stay somewhere else for a few months ( not that you should leave your home!)
I rang environmental health nothing was done.
People are so selfish, anyway reading this with a lot of close proximity neighbours please be aware that others are frightened and need peace and quiet as far as possible.
