Multiple solophobes, in common company, run the risk of long periods of inaction, locked into the avoidance of negative feelings, but unable to seek positivity. A romantic bond between two undiagnosed solophobes is one of the most powerful interpersonal bonds known to pseudo-psychology.
Solophobia is distinguished from the seemingly similar "autophobia," where auto = self, and phobia = fear. Theoretically, feelings caused by autophobia would remain in the presence of others, but feelings caused by solophobia would temporarily evaporate in the presence of others. The difference between fearing one's self and fearing solitude necessitates the creation of the word Solophobia.
"My dog will scratch at the door to go outside to pee, but when I close the door behind her, her solophobia takes over and she immediately wants back inside, rendering her unable to pee. Dilemma."
"I think I might need to move, my neighbor keeps solophobily trying to hang out, and he smells like hot garbage."
