Internet addiction can be a serious problem where getting absorbed in the screens takes over life to such an extent that it is interfering with jobs, relationships, social life, sleep, or paying the bills. It is an addiction if you want
to stop but cannot
over a period of time. It could be passive - as for example logging in every day to read the same intense feeds covering eg compulsively checking for social media "likes", or some corner of the political spectrum, or ongoing debates in a forum - or it could be active - as for getting absorbed into arguments , or maybe 2nd lives, that you cannot seem to stop.
