To be honest, when I play at the casino, I only play for fun and make small, consistent bets
Playing for fun is the best way to overcome gambling disappointment. And in gambling both the slot and crash games are lucky and chance oriented and anyone that comes the gambler takes. But when playing with fun, and you loss, it will still painful but it will not painful as the gambling to win profit or gain.
It is good to use small amount to gamble so it will not be painful when losing. But one thing is that when you gamble and win big you will be motivated to gamble higher and that will lead to another dimension of gambling.
If you will stick to this mantra, it means, you are only spending not so big amount in gambling because you only play for fun. And you won't have financial issues because you surely stop when you already busted your budget. This is actually good because you won't resort to borrowing money or getting more money from your savings just to continue your games.
Also, it also translates to the reasoning that maybe, you have other important things to attend to and gambling is just a side hustle that you keep it just like that.
