Many people who started gambling just for fun have become addicted to it. This addiction pushes them towards various vices they start doing bad things to earn gambling money. Gamblers lose control when they repeatedly gamble to win back money lost in gambling.
As everyone says, it's always about fun. It's more of the time that we're having fun but we are not noticing that we're already starting to become addicted. And when that time comes that we're uncontrollable, we are acting like we're not the real us. Those that have been onto that point and were able to lose as much as they can, although it's like OP has got that record from this point and I know that there are others that have lost more than his.But when you can't control yourself anymore and that's due to you being a compulsive gambler and you can't also accept defeat. You don't know what to do, you'll have hard time recovering from yourself. And the money that you have lost will not be easy to recover, trust me. Even if I am the type of gambler that don't lose big money but the losses that I have made is like a pain in my heart that can't be healed quickly.
