Please notice that grief is natural and normal. If you care about someone you will grieve for them because you have suffered a loss. People grieve in different ways and go through different stages. For some people grief brings on feelings of regret or guilt. Some go through prolonged periods of depression.
Most people eventually get to the stage of acceptance and hope.
Notice also that Grief takes time . No one hurries Abraham. We don't know whether he wept for hours or weeks. Most people have barely begun the grieving process when the funeral is ended. If after several weeks a person is still sluggish from grief we often are uncomfortable.
