There will always be a state or feelings of inferiority complex especially dur to a situation whereby you encounter loss while trying to to achieve something and it'll seem like there's no more hope after the loss, so that's the reason most people nurse that fear of trying again after that great loss. But mostly what I usually let people consider basically in gambling is that they should always set up their minds to receive something as this so when it comes there won't be any cause for alarm.
In gambling it works exactly like that. When you start playing, even when you are just making a deposit, you should already be prepared for the fact that there will be losses. And you need to know how to manage your deposit so you can get through a streak of losses without it seriously affecting your balance. Of course, losing will be frustrating, there is no way around that, but if you are mentally ready for it, it will be much easier to handle.
