Interesting - I didn’t know there was a term for it.
Most people don't know grief researchers actually have a name for the wave that hits you out of nowhere, years after a loss, for no clear reason at all.
Psychologist and grief researcher Therese Rando coined the term STUG reaction back in the early 1990s, short for a subsequent temporary upsurge of grief. It describes exactly what it sounds like, a sudden, intense wave of sadness or emotion tied to someone you lost, showing up long after you thought that grief had settled. Rando herself compared it to being out in calm water and then getting knocked over by one unexpected wave.
What makes the concept useful is that it normalizes something a lot of people quietly worry means they're doing something wrong. These upsurges can happen even after grief has been carefully and fully processed, and they tend to show up more often when something about the original loss was left unresolved or incomplete.
It doesn't mean you're back at square one. It just means grief doesn't always move in one direction. 🌊
Has grief ever caught you completely off guard like that, long after you thought you'd made peace with it?
