OMG, U must be extremely tired. Gosh, that really is horrible!!!!!!!!!! *hugs*
And extremely mean of them to be doing it to u like that! I wish it was easy for u to just go over and tell them to quiet down but as u mentioned...tht doesnt seem to be the way with things there... i have no solutions for u but i can really feel that is really miserable. I hope things get better soon. While although yes, u shouldnt be the one who suffer, if tht girl's not leaving or going to quieten down, maybe for the sake of ur health, u'll have to move...u need rest!!!!!! and peace!!!!
