Your title pretty much says it all, one shouldn't gamble if they don't have patience of they will gamble away everything that they have since they wouldn't be able to control themselves in the middle of gambling and will eventually just spend every single dime they might have had just like you and regretting after that doesn't do any good at all.
Maybe more precisely, never gamble if you don't want to lose money. Because most people will not be able to contain their curiosity for a bigger win. Not a few of them spend everything on gambling, if you don't want to experience the same thing it's better not to know it at all. To be honest, I myself always find it difficult to hold back when I experience defeat at gambling, it's hard to stop doing it because my curiosity is so great. Indirectly I don't seem to remember anything when I'm gambling, spend everything I have, and always end up regretting it.
If I was you, I would probably just get away from the platform for a while until the transaction is confirmed so that I can withdraw my funds, I have that kind of patience and I'm happy and proud that I do unlike many others who don't.
It's hard to stay away from gambling if you already know it, curiosity always haunts every day, and victory is not the end of everything but the beginning of a downfall. If you have the formula to get away from the feeling of addiction to gambling, please tell me immediately, friend.
