Grief should not be avoided, despite feeling bad

Grief is undoubtedly stressful. It typically involves a long time of sadness or sorrow, but often other 'negative' feelings such as anxiety, guilt or anger. 

The idea that our lives would be better without grief seems misguided.  People assume it's good to try to prevent others from suffering. But in the case of grief, most of us would be hesitant about trying to wipe out the grief of a bereaved friend. Not experiencing grief at all thus seems worse than experiencing grief.
