We all seek to avoid pain and gain pleasure. It’s our human nature. Stress is on the rise as the never ending stream of distractions, responsibilities and information bombard us from all directions. Life in the fast lane demands coping skills like never before. Life is a balance of unwanted and wanted. It's up to us how we react to it.
It may sound odd, but picking our skin is a way to avert negative emotions and somehow get a surge of relief. Not to sound harsh, but like other bad habits such as smoking, drugs or binge eating, this practice is a form of self abuse and self sabotage. Rather than beating yourself up about it, creating awareness around the habit will put you on the path to healing.
