Must of us have experienced homesickness. It’s normal for humans to miss home when they are away from it. Homesickness is a form of nostalgia that is as unique as each individual.
Have you every been homesick for a person rather than a place? It’s similar to just missing the person but you are homesick for being in the same space as them. You miss the realness of them, the being of them.
It’s missing the simple presence of them so much that it physically and emotionally hurts.
That’s real homesickness.
