The death or loss of a sibling is a devastating loss regardless of age or manner of death. Siblings are formative in helping us learn how to deal with our emotions, problem-solve, and behave with others—and losing them can be an unfathomable event that seems impossible to heal from. The grief that an individual experiences when their sibling passes away can often be neglected or not understood to be as severe as the parents’ grief. However, the loss of a brother or sister during the teenage years is shown to impact an individual's future relationships and even career paths, and the loss at any age can shake up family dynamics for the long term. Whether sudden and unforeseen or prolonged and expected, losing a sibling can have a profound and long-lasting impact.
