This sort of thing just happens. Keep playing and you will show a profit with QQ. Try not to dwell too much on past results with a hand if it effects your play.
After I played 10,000 hands at Betfair. My second worse hand was TT. It was at the back of my mind and every time I got dealt TT a little voice in my head said "here's another loser" and it definetly affected my play for a while till I banished the stupid thought from my head. Now after a few more ten thousands hands TT is up where it should be in terms of profitability. This also shows that you really do need to play A LOT of hands before you can draw very strong conclusions about hands.
