I don't think its everyone of us that get addicted in gambling, except if there are situations in which we are addicted and still don't get aware of the whole thing, i see addiction as a misplace on priority for gamblers, i wont blame for some that got themself into this because they have much handling time for gambling than some other gamblers do, but if we are truly engaged in doing so many other activities that take much of our time, we are likely not to be addicted because we don't even have the required time enough to do so.
There is still some addicted gamblers that is aware that they are addicted but their problem is that they can not control their urges of gambling. I agreed with what you said, most times loneliness make us to gamble. Most days I gambled when am less busy because I feel lonely and needed something to keep myself a little bit busy, although I also make sure to deposit little money so that I wont spend much (just the omes I can afford to lose). But am happy because I don't get too close to gamble so that I won't become a victim of addict to gamble.
Many cases occur where a gambler knows about his gambling addiction but still cannot control himself. And one of the reasons is that when a person is alone, he is more interested in gambling. Because at that time everyone likes to be busy for gambling. I myself have a strong desire to gamble when I am alone at home for some reason or have a weekend. Then I have to manage my money anyway. I believe this type of situation often occurs in gambling addictions. Although I lost control at one point while gambling, I was able to regain it later.
