When gambling can't keep itself away from the urge it is considered a mental disorder. At this stage even if a person loses everything for gambling he cannot give up gambling addiction. And when this addiction reaches extremes it wreaks havoc in people's lives.
Addiction is a very difficult thing to comprehend for those that have never experimented, as the addicted takes actions that go against their own interests, but their mind is so warped and their priorities so out of place they cannot understand their lives without gambling anymore, which makes them to sacrifice everything for it, a huge mistake as one day they will realize what they have done, and they may try to get their life back on track and they may find themselves alone without anyone willing to help them out.
It's get way worse of actually the addicted person decides to keep a secret because that only feeds the addiction to a level that is way above treatment and when reaching that stage, selling and loaning off self property can be the main results because he or she will be deeply associated that whatever means it takes to make money the person would try it and do it.
