There are 5 distinct stages of grief.

we going to deny, because the loss is so unthinkble;

we become angry with everyone, then we bargin, we beg, we pray, we offer everything we have,

we offer our souls;

when the bargin failed and anger is too hard to maintain, we fall into depression, despair untill finally we accept that we have done everything we can, we let go.

we let go and afterwards move to acceptance.
