It's not in your imagination! I can't even say hello to unknown people in the street - I can't get the eye contact right and always get the timing wrong. Nothing is ever intuitive.
I felt it acutely when I was nursing and even within AA/NA. It was heartbreaking when so many colleagues seemed to reject or outright bully me. I internalised this shit for years, always trying so hard, reading endless books on social skills/body language yet completely unable to apply any of it.
The thing is the friends you do make are likely to be good ones who relate or don't care.
Now I'm older I'm more than happy with my one 'real friend' who I see weekly and two 'close friends' I haven't seen in years but would be there for me in a heartbeat.
Hedgehog's Dilemma.
Arthur Schopenhauer conceived this metaphor to describe what he considers to be the state of the individual in relation to others in society. The hedgehog's dilemma suggests that despite goodwill, human intimacy cannot occur without substantial mutual harm, and what results is cautious behavior and weak relationships. With the hedgehog's dilemma, one is recommended to use moderation in affairs with others both because of self-interest, as well as out of consideration for others. The hedgehog's dilemma is used to explain self-imposed isolation.
I'm sure many would look at my life of relative seclusion but they're not me. Just because society frowns doesn't mean I can't be happy with my lot and I'm certainly far happier than when I was living a lie.
The internet changed my life for the better, I no longer had to try and make friends just to stave off boredom and the web is full of neurodiverse types.
I've left the preview on because it's a cute hedgehog.
