Sorry to hear about this mate. As someone else mentioned, perhaps it’s the type of game you play? I enjoy gaming and can moderate fine. However, recently started playing Overwatch (hey another Blizzard game) and noticed I got addicted. Couldn’t stop playing, thought about it a lot, etc. Reminded me of being addicted to alcohol or other drugs.
I quit playing OW2, and the urges to play started to get easier, and I enjoy gaming again.
