So glad I found this forum as I am having trouble kicking this addiction on my own. I'm not sure how much I should write here, my story is quite long if I were to explain everything that happened which made me end up here. But in short, I realized I had a problem 2,5 years ago when I had a psychosis. It lasted about 24 hours with smaller persisting for a week. I had been neglecting sleep, smoking weed regularly, and drinking heavy every weekend for at least a year leading up to it. I was not happy, and I was doing everything to not confront that fact.
After the wake-up call I went into therapy, initially for alcohol and weed but I was able to quit that over night without problem (I just needed a good reason to quit). So I focused on my addiction to gaming (mainly League of Legends) in the therapy, and after a couple of months I was completely "clean".
Now, my problems have started again with the release of WoW Classic, a game I used to play with my brother and friends as a teenager. I desperately wanted to relive the nostalgia. I set a goal of 8h / week, max 2h / session, and never later than 10pm. That didn't last long and I was soon consumed with the game, thinking about it constantly when I wasn't playing, and lying to my girlfriend about how much I actually play. I was able to see the problem and quit for a month, but now I'm back again.
I am still not sure why I can't just play moderately. I am happier than before the psychosis, but apparently not enough to resist the pull of this alternative world. Maybe I am just lazy, confronting emotions is hard work and gaming is the easy way out.
