All grief is personal and you should be able to deal with grief in the way that is most helpful to you, but the same is true for other people who also miss your loved one, even if they are from a culture that deals with grief in a different way.
Each culture has its own different mourning ceremonies, traditions, and behaviours to express grief. For example, some peoples’ belief in a life or existence after death helps them deal with the pain of the loss while others believe they will be born again to a better life. In some cultures, the spirit of a deceased loved one directly influences the living, and bereaved family members may be comforted by knowing that their loved one is watching over them.
