Do you mean the problem of separation from society? This problem concerns not only gambling - many online gamers or some other games become fanatics of this activity and forget about everything else. I heard in China there were cases when players died right in the gaming clubs due to the fact that they forgot to eat/sleep.
I'm an online gamer and I felt this. Separation from society.
Whenever I go out, I'm comfortable if I'm alone compare to the times where I got some friends if I'm outside. You said that there are cases in China who died because they forgot to eat/sleep. That only means that they are in a gaming addiction and many are experiencing the same thing as they've experienced. Lucky for me, I can control myself whenever and I can manage my time. I know how many hours will I play, go outside, eat and sleep but there are times that I take lesser sleep hours than the usual but I only do it once a week (mostly on Fridays) because of my current work too.
The feeling of comfort from being alone is probably not related to desocialization from games. I think this is just a stage of growing up.
The fact that you follow time management and do not allow games to take your time from necessary things such as sleep and work suggests that everything is fine with you and you have no dependence with which you should fight.
