crazy variance

[mrtal]

Trying to make sense out of this, last 8 nl sessions losing. Aa vs a5. Aa vs ak. Kk vs k8. Kk vs qq. Aa vs qq. I had all my money in preflop with almost every hand as a huge favorite and keep losing. I'm down all my nl profit almost 3000$. Game is 1 2 nl and 5 5 nl. What can I hope for to change? I've only won 1/10 hands with kk or aa heads up.
