If you are degenerate gambler and everything you care about and need rides on the result of a game, then of course you will get depressed. I used to be like that, for a while but I quit while I was ahead and now it is all about making the Benjamin's. Gambling is no different than running a business to me now, and when I have money on a game I usually don't even watch it. I realized that I can be doing better things with my time than sweating games all night every night. It's gotten to the point where putting money on the line for a game and seeing that I lost the bet has no emotion to me anymore, because I remember I am ahead and will come out a winner in the end. I guess it can also be how you look at betting, but that is just the way it is to me now.
