STUG - Sudden Temporary Upsurges of Grief
Sudden Temporary Upsurges of Grief (STUG) – These events produce a reaction with periods of intense grief, which occur when a catalyst reminds one of the absence of the loved one, or resurrects memories of the death of a loved one, or feelings about the loss.
These reactions can be expected and can happen in response to anniversaries, birthdays, and family celebrations.
Or they can be unexpected in the form of a song on the radio, a smell, or something that is read or seen that brings up a memory of the loss.
They tend to catch the individual off guard (Rando, 1993).
