Any and all addiction is the need to suppress emotional discomfort.
Whether it be substance abuse, technology, shopping, procrastination, etc.
We get caught up thinking we are chasing something (a high, feeling, adrenaline etc). The solution is learning to experience/express our current reality.
Our emotional range from Joy or Love to Anger, Fear, and Sadness.
When we learn to express any and all of us, our need to escape ourselves lessons.
And therefore, our need to run safe, addictive behaviours gravitate towards behaviours that help us grow and develop.
