It appears to me that, like many others, there is an issue with the quality of your interactions, and you are unable to control when/where/how they happen. I sometimes hear the phrase "People are social animals" to express the sentiment that living in densely-populated environments has a good/neutral influence on the human psyche. The disclaimer should be that socialising with people we know well and trust is what's "natural" and yields benefits; being constantly surrounded by strangers has to be stressful for us. Wether consciously or intuitively (See the excellent book "The Gift of Fear" for more), we are constantly scanning our surroundings for potential threats. That, and a lack of accountability for how one treats their "neighbours", presents problems that can place a tremendous load on your mental health.
