One of the most difficult phases in any life transition is the space of the unknown between a loss or change, and healing or new beginning. All life changes, even positive ones, entail a sense of loss or grief. For example, there is a sense of loss in giving up addictive behaviors like cigarette smoking, despite the fact that the change is a positive one. Even the change of getting a better job or promotion entails loss — you might be giving up security, relationships and the comfort of the known in making such a change. The most difficult changes involve the death of a loved one or death of a relationship.
