I don't get it about "stage" thingy. Still depressing though
The Kübler Ross Model of Grief states that when one is confronted with death (not in any specific fashion) they will go through 5 individual phases, where they deny the possibility of death, are enraged at those around them, will bargain with with either their caretakers or a higher power, become depressed and retreat inward, to then finally move on and accept the inevitability of death.
