I quite agree; I'm there myself. Tired of being judged, picked apart, and rejected. I've realized that everything is contaminated at the core and that "connection" is nothing more than a transitory illusion built upon favorable misunderstandings that give out sooner or later. It feels far better to just stop rather than repeating the failure in an endless loop. The worst thing isn't being isolated - it's struggling in desperate futility to build and maintain these so-called "relationships" with people, being tortured by them.

I hope that stepping back from humans will ease your pain somewhat.
