Especially with trauma, and sometimes because of present unhappiness, one goes back in their minds to try to work out or learn from what did or did not happen. This is just the way the mind works. It wants to go over and over events in hopes of avoiding mistakes and changing the future.
Looking back can be healthy, or it can become obsessive and keep us from fully living life today. If you are reviewing or feeling the past in a way that is not productive, it is often a good time to reach out to another person so that the past can be put into perspective. After all, the present is the place where we can ultimately find peace with the past.
Good Luck Today,
