the only drawback of making official complaints is that you must declare a dispute when you sell the property. that's assuming you're not renting.
i have similar issues (but not nearly as bad as you, sympathies) with 1 neighbour in particular and a couple of others who are randomly noisy.
given the one neighbour's varied and constant irritations I find it very very hard to be rational about the others when they start too. altho it's actually pretty infrequent.
i've got my property on the market so am loathe to make an official complaint but i am keeping a log just in case. part of my problem is that there's a history of drug dealing from that flat. when i bought mine/moved in he was in jail after the place was raided. not information that i was given during the sale
anyway, sorry i've waffled about my own situation!
hope things settled down for you last night and i would suggest seeing your MP at their surgery and asking for help/advice.
also, contact the police and find out about how to make an anti-social behaviour complaint so that official records are being kept.
go to the dr too and tell them your housing situ is giving you stress etc!!!!
is there any mileage in considering moving? can you and your other neighbours join forces and get some sort of formal group complaint into the landlords of the property?
you have my sympathy, hope things get better soon.
