Where exactly the line is between 'withdrawal' and anxiety caused by a sudden, non-voluntary change in habits, I'm not sure, but I'd say that the one looks very like a symptom of the other.

If we're willing to admit gambling to the list of things that can be addictive, then I'm not sure why other dopamine-related compulsive activities shouldn't be treated the same. Restlessness is well known as a gambling withdrawal symptom.

If everything that people do out of habit and like and you taking it away causes withdrawal, then .... What is the significance of this at this point?

I'm not sure that "everything that people do out of habit" is a reasonable summation of the category we're talking about. Perhaps I misworded my post above.

Gambling is known to be addictive and causes some symptoms of withdrawal when stopped suddenly, even though it is not a chemical dependency and doesn't involve introducing a chemical into the body.

So if we allow that one chemical-free activity can be addictive, I don't see a particular reason that we should exclude the possibility of other things working that way too.

I'm not saying the other poster is wrong that it could be "her daughter suddenly feeling socially excluded after having filled the void by social media", but I think it would be wrong to exclude the possibility that the removal of the dopamine rollercoaster of social media is causing anxiety directly in the way halting gambling does. And the description certainly comes across as someone who is going through a form of withdrawal - it's familiar to me as an ex smoker.
