孤单成性不治是病

This phrase translates roughly into being 'habitually lonely,' a state described as untreatable ailment—a kind of loneliness ingrained in personality. The netname conveys a sense where someone admits chronic isolation as intrinsic part of self, acknowledging social detachment but perhaps without intention nor desire to change it, almost accepting solitude as natural. This might hint at underlying issues like anxiety, introversion, or depression.
