I tell you and is very bad for one to go extra miles in borrowing money to cover up for their gambling activities, it's sure a pure state of gambling addiction just like someone that can go miles to smoke or take illicit drugs.
Well borrowing money isn't that bad but the worst thing is that such addicts sell their household things and belongings of their siblings and other family members.
Some addicts often sell their wives items and some even forget all moral values and do worst things possible.
The addicts that are highly addicted don't really have any moral values and they could literally cross all lines.
Anyone that is already at this worst state, expect that he's not anymore at his good and critical thinking. He needs a medical practitioner that will guide and help him throughout the process, someone that he can trust and feel assured that he'll get recover soon.
Acceptance is the key. Being in denial won't help these gambling addicts. It will only make their condition worst, until they don't have chances to recover and feel good anymore.
