You may at first experience a sense of great loss. Mood fluctuations and feelings of isolation and withdrawal may follow. It takes time for you, the grieving student, to gradually return to your old self and become socially involved in what's going on around you. You may find yourself feeling guilty for things you did or didn't do prior to the loss. Accept your humanness.
Many students try to bargain with some sort of deity.
Some try to bargain and offer to give up an enjoyable part of their lives in exchange for the return of health or the lost person. As you go through changes in your social life because of the loss, you may feel lonely and afraid. The more you are able to reach out to others and make new friend, the more this feeling will lessen. Acceptance does not mean happiness. Instead you accept and deal with the reality of the situation.
