What can be beneficial in such situations is adopting a fly-on-the-wall perspective and either writing or narrating an account of the unpleasant experience using the third person when referring to yourself. This approach can create distance between you and the painful event, facilitating more thoughtful reflection and providing a better understanding of what happened.
Idea for Impact: By processing a negative experience in a way that fosters distance between the then (when the event happened) and the now (when you’re recalling it,) you’ll gain control over it, rather than allowing it to control you.
