Mine was betting $100 on red 30 at roulette table on my 30th birthday the lady at the table was like are you sure you want to do that I wouldn't and then sure as shit I say okay fine then lets go with your gut and put $100 on black instead.... Low an behold guess what it rolls a dang red 30 that would of been $90k profit I think I called over the manager an was like yo this chick just talked me out of the bet an you mean to tell me its not rigged made a scene an instead of getting at least free drinks they kicked me out!
Wow, that's so f*cked up, I would be so pissed, but even then, it's you who ended up changing the bet, thus, in the best case scenario, you'd get a few drinks, and in the worst, you'd be kicked out, just like it happened. This incident shows to always trust your instincts,. even if they end up false, because it's your own responsibility to own up your mistakes. Being talked into changing your initial bet sucks, always go with the option you chose first.
As for the OP, I'd advise him to decrease his gambling budget if he's suffering a mental breakdown after losing. I'd rather not see myself losing a considerable amount of money, thus, I prefer to avoid it in the first place.
