There are no right or wrong emotions. Each emotion has a part in our process of healing. We tend to bottle up difficult emotions. This can be especially true for those who feel they must be strong. This tends to create more stress and slows the grieving process.
Unexpressed grief can lead to misplaced anger and unwarranted harshness toward others.
Like other aspects of grieving, feelings of anger, guilt and blame will come and go. They are a normal part of the grieving process. This is especially true if you were unable to be close to the person who has died. If any feeling, image or thought seems destructive or prolonged to you, you may want to consider talking with a professional or pastoral counselor. Grief may also be experienced physically as pain or tightness in the chest, exhaustion, anxiety, difficulty sleeping, and loss of appetite.
