From Psychology Today:
“I can say—after interviewing several of them over the years—that many of us have trouble feeling completely comfortable wherever we are—no matter how welcomed we may be. At times our discomfort can manifest in distancing, indifference, or even rudeness, but we usually don’t intend to insult anybody. We just seem to have an internalized nomadic notion that we don’t belong anywhere in particular. Even when we do settle somewhere we often work our asses off to prove our worthiness—just in case anyone gets any ideas about putting us back up for adoption.”
