I must be frank with you I have never gambled to that extent where when you lose gambling you found it so hard to comport yourself naturally and never allow such things to weigh you down.
What I also sense here is that as a gambler when you are gambling with an amount extremely higher than what you expected then it would gradually brings you down because you are gambling with an amount that is not subjected to lose or risking away. Though we talked about having funds allocated to gambling account; of course it's another major reason all gambler should follow to enable them remains vigilant and positives, even though you are losing it's assumed that such amount that one uses to gambling is not worth of killing oneself to the amount of funds that are being allocated to your gambling accounts.
