Your Brain Confuses Unfamiliar With Unsafe

New job, new city, new relationship — your brain flags all of it as potential danger. That's not a flaw; it's an old feature. The nervous system can't easily tell the difference between unfamiliar and threatening. But discomfort at the edge of something new is not a warning sign — it's your system recalibrating. The knot in your stomach before a first day isn't telling you to leave; it's telling you this matters. Learning to read that signal accurately changes everything.
