500$ is too big just to lose on a gambling session that you didn’t even enjoy. It’s like being rob but worse because you are just exhausted yourself on game that took away your money. I think you should start to learn how to use gambling properly.
I've been a victim of this activity in the past as well, back when I don't have the slightest idea for why I gamble, Initially, and back when I still play almost everyday with my friends, I saw it as nothing but a way for us to bond and have fun together, when that died down I saw it as a means to earn quick cash, given the fact that I was good at some of the games too, eventually when that didn't work out I only saw it as a way to relax, massive mistake as this is when I started losing money for no particular reason, and happily I should say, as of now, I only ever see it as a temporary rendezvous that I go to every now and again when I don't feel like doing anything and I haven't been busy.
I implore people to really look introspectively and ask themselves why they gamble in the first place. I know this sounds too preachy but knowing why you're out here wasting money on games is going to be important in the long run.
