Grief has no deadline, and it does not end. It changes. The sharp, constant pain of the first weeks usually softens and spreads out over months, but there is no date when grief is finished, and anyone who gives you one is wrong.
This is the question people are most afraid to ask out loud, because the honest answer, "there is no timeline," sounds like bad news. It is not. It means you are not behind, you are not doing it wrong, and you are not broken for still feeling it. Below is the plain version: how grief actually moves over time, why the "one year" rule is a myth, and the real difference between grief that lasts and grief that is stuck. For why none of it moves in a straight line, read grief is not linear.
