It's possible for them to accept their defeats but there are times that they can go beyond their limits, making them feel bad about it later on. You feel frozen after a loss maybe because you can't believe it happened and you can't think of ways on how to get over it. In my case, I will be panicky and start thinking of ways on how to earn money again.
Yes, even it I play on landbased casino's it was really a great experience and you will not think of the money that you loss that night. Maybe you can afford to lose it, or it was just the experience of playing in a casino again with so many people around you winning big.
But for others, specially in online, it's very hard to get over, maybe the best thing to do is to really quit that game and not think about that money. If you don't have someone to talk to in the house, just browse the net and look for positive thoughts so that you can forgot about your bad experience that night.
Getting over with losses or on times of frustration then it would be most likely be on distracting yourself via doing other activities or hobbies that you do have.
You should really prepare yourself with those disappointments once you had decided on touching up gambling.It do involves lots of winnings and losing
scenarios which you should make yourself able to accept on those things on point.
