I think my problem is that I'm just on my worst losing streak on the graph. Nothing's going my way on any hand, such as losing to a double riichi, getting ron'd when I riichi, discarding a tile discarded only two turns ago and getting ron'd, close to a flush but not picking any tile in the suit, and so on (the so on is every hand had something horrible happen). I'm not playing any worse then I was on my winning streaks so I'm sure it will pass eventually and should be even better if I keep up the defensive strategies I've learned (which has done me no good so far due to my horrible luck).
EDIT: Next game, I was one away from a good hand and got ron'd for half my points (the other person had only recently pon'd something so I had no clue he was even close). Next turn I didn't have any 100% safe tiles when someone riichi'd, so I just tossed one of the tiles for the heck of it and got hit with an ippatsu six dora that took 24,000 points, making me lose everything on only the second hand of the match. Let's just say I'm done for tonight.
