It's okay @diamondinthesky . At some point, we just want to go back to the past and wish to undo our past actions and decisions. But the reality is, we are already living in the present and as much as we want to dwell much on the past—we can't do something about it. The only choice we have is to make the best out of our present situation so that our future self will be proud of us.

You are absolutely correct Ma'am @maryjolly
