I tend to be very critical of myself, but I believe it might be healthier to confront and acknowledge my flaws rather than allowing others to find and exploit them. Being honest about my feelings and vulnerabilities can help protect me from being hurt by others' actions or words.
Sometimes, taking control of my emotions and breaking my own heart first can feel like a way to regain control, instead of waiting for someone else to hurt or disappoint me. It suggests that self-awareness and honesty may ultimately be a form of self-preservation.
