Move house! Revenge is a deadly path - If your neighbour makes you miserable, like seriously fucking miserable, it is best to move, I know it sucks, but once you settle into your next place, you will feel a lot better for doing something about your situation. Neighbourly disputes can get way out of hand, I have been there, trust me, I eventually moved and currently live in a good neighbourhood with decent neighbours, it honestly makes the world of difference if you are happy with where you live and the people that surround you.
