Final answer:
Guilt and anger are common and natural painful emotions associated with the grieving process, which is factored into the widely recognized five-stage model of grief proposed by Elisabeth Kü;bler-Ross.
Step-by-step explanation:
Guilt and anger are indeed painful emotions that are often experienced during the grieving process. When it comes to dealing with the loss of a loved one, such emotions are actually considered a natural part of the healing. The five-stage model of grief, devised by Elisabeth Kü;bler-Ross, includes denial, anger, bargaining, depression, and acceptance as steps people may go through. Not everyone will experience all these stages or in this order; individual experiences with grief can vary widely.
Teenagers and young adults may confront these emotional reactions for the first time upon the loss of a grandparent or other elder, and it can serve as an impactful introduction to the reality of loss and their psychological and emotional responses to it. It is important to understand that these reactions are part of a normal process and to use metacognitive tools to manage them.
