The intensity of bereavement is dependent upon many factors. The grieving process however can be especially difficult for those who have lost a loved one to a sudden, violent death. In some cases the bereaved may suffer from post traumatic stress disorder, experiencing flashbacks, recurrent nightmares, emotional numbness and impaired memory or concentration. Grieving the loss of someone who has committed suicide can also be especially difficult. It is not uncommon for the bereaved to feel guilt, shame and denial. It can also destroy an individual’s willingness to trust others and form meaningful relationships.
