It's a reality and serious thing for those people who become addicted to escape the reality.
We don't know what they are going with their lives and they've found comfort with gambling.
Indeed loneliness can also make him addicted by often playing continuously no matter the victory or important defeat that feels comfortable for him then that's where emotions are very uncontrolled and continuous victory can become addictive, feel confident and after being defeated they will continue to try again and again too , the level of someone's addiction is indeed very different, there is something beyond human reason.
It becomes a practice and someone who's going through with emotional problem doesn't even think if its already too much for him to gamble.
Until he never notice that it's already too much that it causes him more problem but in the latter, he'll take notice of that. I feel bad for our fellow gamblers that are doing it because they feel something deep within.
