Lastly, I deposit 1800$ to have a better bankroll again, This time I’m betting like a high roller and lucky manage to recover my losses and bag 150$ profit.
You are indeed lucky, because this is just the way people start to gamble with small amount of money and later go for bigger amount like your savings or all the money that you have with you. What will later end it is the person finding himself that he got no money again as all has been used to gamble. Just quit gambling for now to have a better mindset. Do not go more than your gambling budget anymore, because you are lucky today, tomorrow may be very different.
It's normal for gamblers to lose as long as the amount is manageable to lose. But in your case OP, if it weren't you're lucky, then you must have lose a huge amount only in just a blink of an eye. Good thing you realize immediately that gambling will never be good enough if you keep on chasing even small losses. But I agree to what Oshosondy has said, you have to take a break from gambling at the moment because what you have experienced is a terrible one. You can manage your loss at the moment but I don't think you can still be able to do it the next time you gamble.
Gamble for fun and not to earn profits or chase your losses. Otherwise, if your mindset is like that, then you are not doing healthy gambling anymore as you get more attached to chasing your losses than to just simply enjoy and have fun when gambling.
