Heads up Sngs and Cashgames

I just finished playing 3 more HU sngs and even though 10 is a very very small sample im starting to wonder if maybe i just cant beat them...well beat the rake actually because after winning two and losing one im only up $3.75 on all my HU sngs. I really want to get better at these but it seems sorta weird that i can dominate HU cash games but cant make a profit in HU sngs. In my hr and a half session two tabling 25nl i ended up down $8.75 after losing a $34 pot w AQ to AK on an AAx board so thats always fun. I think im about to see if i can find someone sitting at 50nl by themselves to try and catch up for the day but if not oh well there is always tomorrow
