I lived in downstair in apartment. and Only one lady lives in upstairs. shes about 54 years old and asian She walks SO hard& loud everyday (morning / afternoon and even Night times) I don't care if she uses bathroom at 12 am or 1 am because that only takes about less than 5 mins. but she walks hard and i heard washing dishes by hand at 1 am or 2am even my 2 years old son wakes up in 1 am or 2 am because of pounding sound. I can't sleep so I'm taking tranquilizer me to get sleep from my DR. I sleep only 2-3 hours night If i try to sleep in the morning because i couldn't sleep night she makes too much noise again in the morning thats why i want to sue her or something i want to know what can i do? 1. can i sue her from giving me stress? 2. is it legal to hit my wall to make them a noise?
