next time when you feel hopeless and depressed take a line of coke cheer up and retry your bet.
I feel your spirit in gambling and you are trying hard to regain the momentum and got lucky. But the risk of doing this is too high and not all gamblers can do the same. It is really a moment to enjoy after recovering from your big losses but not really sure if you can do it again.
Gambling can't always have a piece of luck but most of the time is bad luck. I understand what you are thinking after losing, you are chasing the money you've lost by putting in another huge bet which I believe was not really the best thing to do.
