Homesickness is the sad or lonely feeling you get when you are away from home and miss it very much. It often includes missing familiar people, places, and routines.
From “home” plus “sickness,” modeled like other words for painful conditions. It appeared in the 18th century when long‑distance travel and migration became more common.
Homesickness is your brain’s way of saying, “Your safety map is gone; please find familiar ground.” Studies show it’s not just about missing a place, but missing your role and identity in that place. The odd part is that you can even feel homesick for a place you didn’t like much once you leave it.
