I have always struggled with a cluster of issues... too much tv, too much internet, for a period in college binge drinking, overeating... the big "aha!" was that I was engaging in these behaviors to escape reality.
We live in a unique time where if you don't like the reality you're in, you can step into another. Society has rightfully developed stigmas against other harmful behaviors. But the issue is a level deeper.
For the first time in history, we can "escape" or "drop out" or whatever you wish to call it without chemicals. It's a powerful urge... after all, if you have a limited time on earth, and the world's information at your fingertips, it becomes extremely tempting to just tune out... everything.
