All these addictions look very similar when you dig into the common points of each. I'd recommend Johann Hari's exploration into addiction / depression. He describes the root causes/commonalities in very accessible ways. Helped me understand what is happening in myself and others. A lot of what we treat as normal begins to have an addictive element to it when taken even slightly too far. Social isolation isn't good for you and it causes ripple on effects. That's just one cause of addiction. Most of us have many factors simultaneously. This doesn't imply you're now an addict but the tendency is in place.
