everyone feels like this sometimes, and i don't think you're alone. a bottom line is, most people aren't greatly successful poker players, that's just the way it works. A big majority of people will lose a tiny bit of money over time, a lot will win on a small scale, and a few will win big. If you like poker, and want to keep playing, (and you are not addicted, as in this time your are spending is not being taken away from important studying, etc.), then I'd say keep trying. Go buy a few books, try to see things you can improve, watch rippy and michael and see if you can learn anything from them, buy pokertracker, read more/post more hands on here. you can improve if you can keep your frustration under control, which admittedly is hard.
