One influential approach is Simon Shimshon Rubin's Two-Track Model of Bereavement, which focuses on both day-to-day functioning and the evolving emotional relationship with the deceased. George Bonanno's research further shows that most people demonstrate natural resilience, experiencing stable functioning despite significant losses, while acknowledging that grief can manifest as sadness, anger, anxiety, laughter, or even numbness. In some cases, however, grief can become prolonged or debilitating, leading to complicated grief or prolonged grief disorder (PGD), where persistent longing and difficulty resuming normal routines interfere with life. Certain losses, such as the death of a spouse, child, or parent, tend to carry higher risks of depression and other mental health challenges. Studies on biological and cultural differences reveal that expressions of grief are highly diverse, while evolutionary theories suggest grief may help...
