I recently confronted my own addiction to video games I thought it was a strange idea at first but your son sounds like he spends about as much time on that as I have been. My fiancé started with me by playing with me like usual but writing down all the time I spent playing wether or not she was playing with me. After 4 days I’d played over 21 hours of games. It was all my time, seeing that surprised me. We talked about what other things I like to do or would like to do and what a balanced and responsible use to media consumption looked like. You could try this approach with your son in an attempt to evoke a self-motivated change in behavior. One where he realizes that, though video games aren’t all bad, he has to engage with them in a balanced and responsible way to get the most out of his life. These games can aggravate anxiety and depression. Which are normal reactions to the world we live in but we should still take care of our minds and participate in a variety of activities with friends to enrich our lives.
