We almost got the same story. You atleast have a house and can smell your bad Body Odor on the towels.
Me, i live in a building so i have to deal with pissed off neighbors who slam doors and slam things. So that makes my heart beat faster and makes the Body Odor smell worse. How i know even though i can't smell my own Body Odor ? well the neighbers start hiting and slaming things even louder.
It's just a f***ing nightmare like you said. If you confront them they act as if they have got no problem and everything is ok. My parents not being able to smell me doesn't help. My parents just think the neighbors are just loud. sheesh
