Why do certain memories stick with us like photographs? Neurologically, the brain processes images 60,000 times faster than text. Traumatic events often get "stuck" in the amygdala as vivid, frozen images. Likewise, cravings or depressive moods are often triggered by mental pictures (a specific bar, a person, a moment of failure).
A diagnosis (e.g., "Severe Alcohol Use Disorder" or "Major Depressive Disorder") is a label on a chart. A mood is a living, breathing environment. You cannot change your diagnosis by looking at it. You can change your mood by changing the pictures you allow into your mind.
