Physical and Emotional Pain= all the same in the brain

This article makes me wonder whether cutting is prevalent among adolescent girls because it mimics internal emotional pain that can't necessarily be appropriately expressed. It's also interesting to think that future treatments for psychiatric issues could be physically based and physical problems can be treated with emotional boosters. Do you guys think that maybe having more adolescents involved in sports (since physical activity has been found to increase mood-boosting hormones and decrease self-reports of somatic pain)could reduce cutting frequency or risk by acting as a physical outlet for internal pain?
