The other day I lost a few $ gambling on Roobet. My luck was so bad that day that when I thought of gambling a little more so that I recover the lost funds I lost more than 3 times the amount I lost earlier

Eventually I just quit the game and didn't play it again for 2 days. This is too obvious for any gambler and everyone can relate to this feeling.
You are making the right decision. You don't have luck at that, chasing the money that you have lost in the past days will just help you more to lose again. Quitting is the best solution, we don't need to force nor to push ourselves into making another bets that we know that we have no luck this time because the chances of winning is clearly nothing.
