Denial-"this can't be happening to me", looking for the former spouse in familiar places, or if it is death, setting the table for the person or acting as if they are still in living there. No crying. Not accepting or even acknowledging the loss.
Anger-"why me?" feelings of wanting to fight back or get even with spouse, anger at the deceased, blaming them for leaving.
Bargaining-bargaining often takes place before the loss. Attempting to make deals with the spouse who is leaving, or attempting to make deals with God to stop or change the loss. Begging, wishing, and praying for them to come back.
Depression-overwhelming feelings of hopelessness, frustration, bitterness, self-pity, mourning loss of person. Feeling a lack of control, feeling numb, or feeling suicidal.
Acceptance-there is a difference between resignation and acceptance. You have to accept the loss, not just try to bear it quietly. Realization that it takes two to make or break a marriage. Realization that the person is gone (in death) that it is not their fault; they didn't leave you on purpose. Finding the good that can come out of the pain of loss, finding comfort and healing.
