Hi, im new here, whats up?!

Im having a really, um silly(?) i guess, problem. See, im having a problem to keep the stack that i have managed to get earlier during the day/night/evening... Take yesterday for an example.(these numbers does not match, exactly, to what happened.. but almost) I put in like $50 on my account. Sat down on a table, $.5/1 ... not to long after that, a few hours, i was up to like $300 Then i caught a bad beat, someone got a perfect runner runner, i was down to like $250 ... a few hours later... i was at $0. I mean, no big lost, i started out with 50, so no biggie.. but this keeps happening, Alot, wether its on cash games, or on tournaments. Tournaments goes abiiit better, but it Could go way better if i just figgured out what im doing wrong. anyone experienced this and have a way around it?! im :Frusty: right now..
