Exactly, when you keep thinking about gambling it turns out to be you are somehow addicted to the casino games. Logically, as an addicted gambler you gonna deposit and play more while there are other important things in life to do. Quitting gambling is not easy for an addicted person, there are many variables gamblers should take into consideration before deciding to quit it completely but as you explained once you decide to do so better not to rethink gambling and its consequences, IMO. Just decide what you wanna do and follow this path with help from a professional psychologist.
It is the uncontrollable urge to gamble that keeps a person depositing and gamble. Even if the money is for the monthly budget or payment for bills, a gambling addict will use it just to satisfy that urge. Since gambling addict use the money they cannot afford to lose, they will then chase losses and continue gambling just to recover the lost amount. This is when they are trapped in a loop. Trying to win back the money but keep losing more.
A player is lucky when he realized that he is addicted to gambling and seeks the help of a professional psychologist and therapist since many tends to deny it and continue their gambling addiction until their life is in ruins.
