This is very real man, I used to be addicted to games as well. I think what really helped me with my addiction is finding something else to replace it. When you quit all of a sudden like that you need another activity otherwise you will be bored and that's when anxiety kicks in.
I recommend this book "The Power of Habit" - by Charles Duhigg
Hang in there man!
You are 100% right.
A lot of people say you need to occupy your time with other things.
I've tried A LOT of different things, but I always just come back to gaming.
I still enjoy my other hobbies, it's just hard to break the gaming addiction...
Thanks for the encouragement!
