Sounds like the newbie circle of death to me. You shouldn't play another hand until you figure out what went wrong. It could simply be variance and what went wrong is that you were playing above your roll. It could be that your play was simply unprofitable and it didn't show at first but came back fiercely. Whatever it is, figure it out, then go again and don't screw up in the same way.

If you're in question on if you screwed up in a hand, post it, preferably without results to start. We'll let you know if you screwed up.
