I used to do everything quietly, but after a while this created this current "by product" fear you could say, which is if i make body movement someone else will make a sound in same time i move. By that i mean if i'm sitting in a chair this nervous energy will build up that as soon as i get up from my chair i will hear my neighbor make a sound so they can escape my nervous energy. And the weird thing is that it happens alot. Like it would be all quite (no sound) in aparment, then when i get up i hear someone make a sound same time as i got up. Which is crazy....The aparment could be quite and I could have my arm resting, then as soon as i move my arm i hear someone make sound at same time.
This all stemed from my doing everything quitly, because when shut the door VERY quitly it would live a lingering nervous energy which i think my neighboors could feel so they would make sound through the wall or i would hear them get up from there bed to escape the lingering nervous energy i made from doing things quietly (shutting door quitly, getting out of bed quitly, etc.).
After while i thought in order for me to end this fear of hearing my neighbors making sound same time as my body movement, i would need start making sounds/noises and stop doing things quitly. So i moved to a new apartment with my mom/sister and stopped doing things quitly. I watch TV with high volume , didn't whisper when talking to my family, didn't shut doors quitly. However, this didn't stop my fear of neigbors making sounds same time as my body movement. I seriously which i never did things quitly because i wouldn't have this fear of simultaneously.
