The overbearing sensation of the constant background noise of everything that is going on smothering the living hell out of me.

Are you a social media user? I mean, FB, twitter, Instagram. Allow me to share my experience: I left FB in 2016 and never joined Instagram etc etc. The relief of not being bombarded with useless information (noise) has been great ever since. Sometimes less is more. And don't push yourself too hard to be fully content, it's alright to just go with the flow.
