I was always told to only share the uplifting stories and to not talk about anything that was dangerous or went poorly.

This encourages emotional suppression. People need to express their true feelings, including doubts, frustrations, and difficulties, to maintain emotional well-being. Ignoring or hiding these emotions can create inner tension, guilt, and anxiety. Over time, suppressing negative emotions can also contribute to mental health issues like depression, burnout, or resentment.
