First of all GO OFFLINE. Do household chores,read books,watch movies or tv ,go out and have a walk. If possible visit a psychologist.

Any behavior in excess with an element of craving / compulsion & if it takes over your life with significant impact on your functioning is likely to be addiction. You need to first of all commit to stop this with strategies to deal with potential triggers, keeping yourself busy & occupied with interesting activities, practice yoga, meditation etc. Sometimes there could be other underlying issues like depression, anxiety, low self esteem leading to these behavior which needs addressing. If you find it hard to deal with this, seek help. Be assured that this is quite a common problem & treatable. Regards
